Greek and Roman Mythology Essay Example for Free

Greek and Roman Mythology Essay In the times of the ancient Greeks and Romans, there were many things that held similarities as well as things that were not as similar, wondrous trading and agriculture skills, great warriors, architecture, and mythology just to name a few. However, their life values were opposing, the Romans were more apt to take what they wanted without regard for life, whereas the Greeks were more in tune with Nature. The Mythology that they shared was similar but different in the aspects as how they saw their deities. Their Gods and Goddesses were not worshipped as that of the Christian God of today. The Greeks were more focused on life here on earth and the ideas and thought that a man’s worth was judged here in this life and his good deeds and services would follow him onto the afterlife. Whereas, the Romans believed that good deeds done on Earth would follow them to heaven, if they were done properly and enough of the good deeds were done, then they themselves would become Gods. The Romans deities were not gender specific because they did not have characteristics that were associated with their actions, unlike the Greeks God’s and Goddesses. When you read about the Mythologies of the Greeks and Romans, you will hear the similarities in the stories of their deities. One of the famous Goddess names you may remember is Venus, the Roman Goddess of love and Aphrodite, the Greek Goddess of love, they both share the same aspects of being the Goddess of love. There has been little to no influence of these cultures religions on today’s society, however, one cannot help but wonder, what would the world be like if they had progressed†¦ References Noriega.

Natural Disaster :: Earthquakes, Tornados, Flood

Debris is scattered for miles, houses are destroyed, trees are bent, and vehicles have been thrown. This would be an aftermath of a natural disaster. Natural disasters come in many forms such as earthquakes, tornados, floods, blizzards, fires, and volcanic eruptions, just to name a few. Every type of disaster is not subjected to one specific area. This means that people in certain areas only have to prepare for those disasters that are likely to occur in their region. Throughout the world, natural hazards are a frequent occurrence. On a range of scales they create disaster, destruction and deaths of people. â€Å"A natural process only becomes a natural hazard when the risk of human loss is presented.† (Page 2) An earthquake is â€Å"a sudden shake of the Earth's crust caused by the tectonic plates colliding.† (Page 2) The vibrations may vary in magnitude. â€Å"The underground point of origin of the earthquake is called the focus. The point directly above the focus on the surface is called the epicenter.†(Page 3) Earthquakes by themselves rarely kill people or wildlife. â€Å"It is usually the secondary events that they trigger, such as building collapse, fires, tsunamis and volcanoes, that are actually the human disaster.† (Page 5) Earthquakes may last only a few seconds or may continue for up to several minutes. They can occur at any time of the day or night and at any time of the year. â€Å"They are caused by stress that builds up over time as blocks of crust attempt to move but are held in place by friction along a fault.†(Page 8) â€Å"When the pressure becomes stronger than the friction holding them together, adjoining blocks of crust can suddenly sl ip, rupturing the fault and creating an earthquake.†(Page 10) Volcanoes can cause widespread destruction through several ways. â€Å"The effects include the volcanic eruption itself that may cause harm following the explosion of the volcano or the fall of rock. Second, lava may be produced during the eruption of a volcano. As it leaves the volcano the lava destroys any buildings and plants it encounters. Third, volcanic ash generally meaning the cooled ash - may form a cloud, and settle thickly in nearby locations.†(Page 14) The main killer of humans in the immediate surroundings of a volcanic eruption is the â€Å"pyroclastic flows, which consist of a cloud of hot volcanic ash which builds up in the air above the volcano and rushes down the slopes when the eruption no longer supports the lifting of the gases.

Ankle Sprains And Injuries Health And Social Care Essay

Ankle is a complex articulation which is categorized as a flexible joint joint.It is one of the of import constituent for ambulation in humans.Ankle sprains are one of the commonest hurts in athletics.It histories for 20 % of all athleticss hurts ( Bergfeld J ; 2004 ) .In India, incidence rate of mortise joint sprain histories for 0.31 % of the population ( Statistics for ankle sprain ; 2003 ) .The opportunities of re-injury is seen high as 78-80 % despite the continued research in this field. The pathomechanics for ankle inversion hurt is inversion and plantar flexure of the mortise joint joint.There is loss of scope which is attributed to trouble and swelling ( Denegar CR et Al ; 2002 ) , ( Collins et Al ; 2004 ) .Talocrural articulation is primary responsible for the dorsiflexion and plantar flexure motion. The conventional intervention for acute mortise joint sprain is RICE ( remainder, ice, compaction, lift ) .The conventional intervention with early gesture is suggested to be more effectual for bettering hurting, swelling and mobility ( dettori et Al ; 1994 ) .This shows that the opportunities of re-injury is high because of the ineffectualness of conventional intervention for handling the positional disfunction caused due to acute ankle inversion hurt which makes the joint for susceptible to injury ( Denegar et al,1994 ) . Manual Therapy focal point on the rectification of the postural and motion disfunction due to ankle sprain This method of intercession includes Maitland classs of mobilisation, it is stated that Maitland classs of mobilisation improves the ankle dorsiflexion ( green T et Al ; 2001 ) . .Mulligan ‘s mobilisation with motion technique is stated to be effectual in cut downing hurting and improves dorsiflexion of ankle articulation ( Collins et Al ; 2004 ) . This survey was conducted on topics with subacute mortise joint sprain. The surveies done on Mulligan ‘s mobilisation with motion technique in acute mortise joint sprain are really rare one of the survey done is the consequence of Mulligan ‘s mobilisation with motion for the intervention of acute sidelong mortise joint sprain ( T O Brien, B.Vincenzino ; 1998 ) .The survey showed betterment in scope of gesture and functional result and decrease in hurting. However the design of this survey was individual instance surv ey design taking to restrictions of generalisation of its findings consequence of Mulligan ‘s mobilisation with motion technique on temporal and spacial parametric quantities of pace showed restrictions in survey design, sample design and statistical analysis ( John-Mark Chesney, Erin Morris ) The demand for survey arises due to the restriction of the old surveies done on the intervention of acute mortise joint sprain y Mulligan ‘s mobilisation technique with motion. Hence the purpose of the survey is to happen the consequence of Mulligan ‘s anterior-to-posterior talar mobilisation with motion technique in acute ankle inversion sprain and compare the consequences with consequence of Maitland classs of mobilisation for intervention of acute ankle inversion sprain. Reappraisal of literature. The reappraisal of literature focal points on following subjects. 1. Anatomy of mortise joint and pathomechanics of inversion hurts. 2. Hazard factors of hurt. 3. Conventional Management of mortise joint sprain. 4. Manual therapy to ankle inversion sprain. Anatomy of mortise joint and Pathomechanics of ankle hurts. Ankle articulation is a complex articulation due to its articles, ligamentous and sinewy anatomy. The anterior talofibular ligament restricts anterior interlingual rendition and internal rotary motion of talus inside the mortice. The conjugate gesture during plantar flexure happens as internal rotary motion and anterior interlingual rendition of scree aided by deltoid ligament. The calcaneofibular ligament restricts inversion of the talocrural and subtalar articulation. The posterior talofibular ligament restricts inversion and internal rotary motion after calcaneofibular ligament and anterior talofibular ligament undergo hurt. Konradsen and Voight ( 2002 ) quoted that an inversion torsion was produced on lading a cadaverous leg, when the unloaded pes was positioned in 30 degree inversion, full plantar flexure and 10 degree internal tibial rotary motion. They besides stated that hit with 20 grade upside-down pes in swing stage follow through forced the pes into full bound of inversion, plantar flexure and internal tibial rotary motion. Denegar CR et Al ( 2002 ) stated that in normal biomechanics the instantaneous axis of rotary motion of talocrural articulation translates posteriorly during dorsiflexion, but in anterior malaligned scree or with restricted posterior talar semivowel the axis of rotary motion is shifted anteriorly taking to joint disfunction. Hazard factors of hurt Assorted hazard factors, both intrinsic and extrinsic have been attributed to predispose to inversion hurt and re-injury. Baumhauer JF et Al ( 1995 ) stated that intrinsic factors like old history of sprain, limited scope of gesture and decreased dorsiflexor and plantar flexor strength ratio, elevated eversion to inversion ratio have been attributed to predisposing to inversion hurt. Eren OT et al 92003 ) stated that high malleolar index ( posteriorly positioned calf bone ) is attributed to predispose to twist. Average malleolar index was +11.5 grade in topics with ankle sprain and +5.85 degree in normal controls. Conventional direction of mortise joint sprain. The conventional direction of mortise joint sprain is initiated to RICE in acute phase of injury functional intervention processs with early induction of weight bearing as tolerated, early mobilisation, proprioceptive preparation, balance preparation has been advocated to supply early functional rehabilitation to topics. The direction of sprain dressed ores on inactive and dynamic stableness, deriving normal ankle scope of gesture, optimum strength of peroneal, dorsiflexor, plantar flexor, invertor musculuss of mortise joint, retraining mortise joint scheme ( Bahr R, 2004 ) Bruce Beynnon B et Al, 2004 ) Kerkhoffs et al 2002 ) stated that functional intervention is superior to immobilisation and surgical intercession in countries of hurting on activity, quality of public presentation on return to sport/work, objectives instability on x-ray positions and patient satisfaction. Manual therapy in ankle inversion sprain. Green et Al ( 2001 ) conducted a randomized controlled test of a inactive accoutrement joint mobilisation on acute ankle inversion sprains. 38 topics with acute mortise joint sprain ( & A ; lt ; 72 hours ) were indiscriminately assigned to command ( RICE ) or AP mobilisation plus RICE. All had home plan. Treatment every 2 yearss for maximal 2 hebdomads was given. Consequences showed dorsiflexion is proved earlier in intervention group ( 11 grade compared to 6 grade from baseline to intervention 2 ) . This showed that talar anterior-posterior semivowel speeds up recovery rate. Collins N et Al ( 2004 ) conducted a double-blind randomized controlled test which incorporated perennial steps into cross over design. 14 topics with grade II mortise joint sprain ( 40 +/- 24 yearss old ) Dorsiflexion in weight bearing, thermic hurting threshold were calculated. 3 intervention status. Mulligan ‘s mobilisation with motion for dorsiflexion. Placebo No- intervention control were studied. The consequences showed that talar anterior-posterior semivowel speeds up recovery rate in intervention with Mulligan ‘s mobilisation with motion. The survey conducted was done on topics with subacute mortise joint sprain merely. T O'Brien, B. Vincenzino ( 1998 ) conducted individual instance survey to look into the effects of motion intervention technique for sidelong mortise joint sprain. The technique was the posterior semivowel to distal fibular while patient actively inverted the mortise joint. Outcome steps used Modified Kaikkonen trial. Scope of Dorsiflexion and Inversion VAS for hurting and maps. Two topics with acute mortise joint sprain were used to command for natural declaration of mortise joint sprain. Capable I underwent ABAC protocol while capable II BABC protocol where A-no intervention stage, B-treatment stage, C-post intervention return to feature stage. Consequences showed the immediate effects of Mulligan mobilisation with motion technique on acute sidelong sprain. Rapid betterment of ROM ( inversion and Dorsiflexion ) immediate lessening in hurting. Restrictions The survey design leads to restriction of generalisation of its findings. Therefore, from above surveies we can deduce that Mulligan ‘s mobilisation with motion technique has a ensuing consequence on mortise joint sprain. The above surveies besides suggest the immediate effects of Mulligan ‘s mobilisation with motion technique in intervention of mortise joint sprain. However, a few surveies have been conducted for the consequence of this technique on acute mortise joint sprain and the surveies which are done on ague mortise joint sprain have restriction in signifier of survey design, samples size, statistical analysis. The rudimentss of those findings consequence of Mulligan ‘s mobilisation with motion technique should be investigated in topics with acute mortise joint sprain. Research Proposal Question Does Mulligan ‘s anterior-to-posterior talar semivowel improves the dorsiflexion in topics with acute ankle inversion sprain. Alternate hypothesis. Mulligan ‘s anterior-to-posterior talar semivowel improves dorsiflexion in topics with acute ankle inversion sprain. Null hypothesis Mulligan ‘s anterior-to-posterior talar semivowel does non better dorsiflexion in topics with acute ankle inversion sprain.

Hispanic Groups Living in US Essay

It is very common for someone walking down the streets of any American city and hears Spanish spoken. The federal government of America coined this term ‘Hispanic’ way back in 1970’s to refer people tracing their origin in Spanish speaking countries which were former Spanish colonies or those who can trace their origin to Spain or its territory. This represents a varied range of countries and ethnic groups with different social, political and emotional experiences. A large part of Hispanics still try to characterize themselves in terms of their individual ethnic identity as Mexican, Cuban, and others rather the whole term ‘Hispanic’. Hispanic Americans, n. d. ) The wide range of the Hispanic group includes Mexican Americans, Puerto Ricans, Cubans, El Salvadorians, Guatemalans, Nicaraguans, Columbians, Central and South Americans among others. The Puerto Ricans, Mexicans and Cubans form the largest part of the Hispanics living in America. (Tienda and Mitchell, 2006) America’s cultural canvas is very vivid as each group brought their respective culture’s specialty with them which has totally mingled in the main force. The Hispanic community has left their mark over traditions, customs and cultures throughout the country and the bilingual education structure of America displays the growing importance in the country as they are the largest minority community. It has been noticed that people from the Hispanic groups have done well in various fields and their progress is something to be watched. The 2002 census showed the Mexicans forming the largest part of the population with 66. 9%, followed by Central and Latin Americans at 14. 3%, third position held by Puerto Ricans, others 6. % and last Cubans at 3. 7%. (The Hispanic Population, 2002) Majority of the Hispanics are native born neutralizes citizens or have acquired legal residency status. They are largely concentrated in the west part of the country especially the urban areas of Arizona, California, Colorado, Florida, Illinois, New Mexico, New York, and Texas. There is a tendency among them to live in family units which are generally large in size unlike the non-Hispanic Whites. In comparison to Whites communities, the rate of unemployment and poverty is much more in the Hispanic groups. Mexican Americans are the one to form the largest part of the Hispanic population living in America and they are also the largest group of White Hispanics. The Mexican immigration could be traced in the past decades as they started establishing themselves in the 1600s in southwestern parts of the country who later became New Mexico, Arizona, California, Colorado and Texas. (Stacy, 2002) The work at railroads and steel industry of the Midwest America attracted them in the 1800s and this immigration is still continued to the present time. Today majority of Mexican Americans are U. S. born citizens. The major causes behind the migration of Mexicans to America are self-liberty, quality education, modes to improve economic condition and achieve good living standard. Spanish is the main language for Mexican Americans, some of them are monolingual. But most can fluently speak both English and Spanish. The attitude of the Mexican Americans is something to be watched as more than 90% of them are literate. Their respect towards others is also acclaimed as their communications are respectful in manner. They are one of the strict believers in the concept of familism (Nash, 2007) and value family considerations over individual as well very much rely on family in times of crisis. Patriarchy is the trend of Mexican American family. Earlier, they used to neglect family planning but at present time they have been active in that. Largely they are the followers of Roman Catholicism. They look at churches as powerful source of hope, faith and strength while spirituality and religion play significant role in times of illness, health and life. Their housing conditions are really bad as they live in colonies not appropriate for living to low-income. Central and South Americans stand second in the American Hispanic population. They owe their origin to different countries such as Guatemala, Venezuela, Costa Rica, El Salvador, Panama, and Argentina among others. These groups of people display a vast diversity due to their different origins. Most of them migrated from their respective countries in the period of 1970s and 1980s when the region was going through political turbulence. Nicaragua, El Salvador and Guatemala were suffering from civil wars that made their people to flee in search of stable life. In the present time too, the immigration is on due to different causes. Although many of them arrived in U. S. as refuges, gradually they acquired political asylum from the state. Cheap accommodation and easy immigrant services made most of the Central and South Americans settle in California. They speak other languages rather than Spanish, which is a main language, such as French and Portuguese. Though Catholicism is the main religion, Protestants and Jews as well as other beliefs are followed by this group. They have high religious values. Males are treated as the head of the family. Due to intermarriage among this group and other Hispanics or Europeans, they have become much diversified. The education level of Central and South Americans is much appreciable than other Hispanics but still they lack behind in employment tin respects of other groups. Third largest group belonging to Hispanic community are the Puerto Ricans as they became U. S. citizens after Jones Act of 1917. (Stacy, 2002) But they are not allowed to vote in U. S. Presidential elections. They are mainly settled in industrial areas such as the states of Connecticut, Florida, Illinois, and New York due to the availability of employment opportunity. Wherever they settled, they tried to hold on their tradition and culture and formed various groups and organizations to support them. Puerto Rican Americans pay huge respect to education but still they maintain a low level than other Hispanics which makes parents encourage their children to pursue good education for better future. They are bilingual speaking both Spanish and English. The expressive nature of Puerto Ricans and their hospitality is well known. They possess high respect for women, parents and elderly people and family units that they even allow more than one family living together. Puerto Ricans are followers of Catholicism and seek support from religion and spiritualism in tough situations. Their approach to health and illness is based on these beliefs. Cubans too comprise a significant part of the Hispanic community. Cuban immigration to America can be traced back to history but the major wave was created during the political turmoil of 1959 which still continues today. They have their bases at Miami, Florida and New Jersey. They can be considered as the most affluent among all the Hispanic groups due to their well performance in education, which led to better employment opportunities and a good quality lifestyle. Till recent past they faced problem in speaking English, but nowadays they have overcome that. The Cuban Americans are very much into their culture that they most often do not show much interest in the Anglo culture. They hold a rather conservative outlook towards politics due to their experience in their native country. They possess diverse beliefs of religion; still Catholicism is more prevalent among them. They stand against communism holds much important place in U. S. The Hispanic groups in spite of their various origins share some commonalities as well some major differences among them. Spanish is a bond that binds all of them, while most of them are bilingual. Approach towards education is another common factor between them as all the groups show very much respect to education as they know it is the only key to good living. Religion too makes them stand on a common platform as most of the Hispanic Americans are followers of Catholicism. Political perspective is one thing that creates differences among these groups as each of them has their respective political idea. Cuban Americans support Republicans as they are inclined towards conservative idea of politics whereas Mexicans, Puerto Ricans, and Central and South Americans have a liking for democrats. Still, Catholic faith, language and belief in their respective culture make them stand on a single platform.

Expository Essay Sample on Human Trafficking What Is the Situation Today

Expository Essay Sample on Human Trafficking What Is the Situation Today For thousands of years people have been buying and selling human beings. From the Pharaohs of ancient Egypt, the ancient Babylonians, Grecian and Roman empires, slavery has been practiced in most nations of the world. In the 16th to the late 18th century, slavery was an accepted part of the economic life of western nations. In the New World, the plantation owners in Virginia and other states used slaves brought from Africa to work their fields. William Wilberforce moved for its abolition in England and the empire in 1833. However, whilst it stopped as a legal practice, it did not stop. What is the situation regarding human trafficking today, and what are the causes of its existence? 1. What form does it take today? The definition of the UN on human trafficking is detailed, but it mainly falls into 3 groups. Humans are trafficked for use as labor, sexual exploitation with harvesting of organs being another smaller group. It involves recruiting, kidnapping, transfer and sale of such persons. Exploitation must include sexual exploitation forced labor or removal of organs. 2. How extensive is it? According to US state department Laura Lederer, human trafficking is the third largest criminal activity worldwide. It is only exceeded by illegal drug and arms trafficking. It has become a criminal industry worth $32 billion a year. 3. Who are the traffickers The traffickers are criminals; however, because of the nature of the industry most do not fit the stereotypes. At the top are the criminal bosses. However, down the line it might be a person who gives a young girl accommodation, or drives her to a destination. What they have in common is they make money from doing these things, which are essential to get the victim to the point of sale. Then come the direct criminals, who knowingly buy and exploit the victims. 4. Who are the victims The victims can be anyone. Much of it starts with fraud, or in civil war situations. For example, a girl in Thailand is recruited as an au pair in South Africa. On arrival her passport is removed, she is locked in a house and forced to work in a brothel, either by threat or violence. Young women in civil war areas like the Baltic region of Europe are kidnapped and forced into sex work. These sex workers are put in brothels, on the streets, in rich men or women’s mansions, and kept as sex slaves. Their owners exploit them sexually, and keep any money earned from prostitution. Others are offered passage to another country, and guaranteed work. They gladly accept however when they arrive they find they are slaves. Most are smuggled into the country, do not know the language, kept locked up and used to do labor, from farming, sewing, house cleaning. They get no pay and work at the will of their owner(s) who keep the money they should have earned. The only thing they have in common is they usually are vulnerable members of society. They are often runaways, have unstable abusive homes, and no employment. 5. What is being done to stop it? The United Nations opened a bureau dedicated to combating this problem. Most responsible governments are recognizing the problem and legislating it into criminal law. However, the problem is complex and huge. The International Labor Organization suggests 20.9 million victims are in forced labor, and other statistics estimate millions are involved in sexual exploitation. 6. What is the major problem faced? Lack of awareness is a major stumbling block. If a woman working on the streets approached a police officer saying she was forced into drug addiction and prostitution, she is as likely to be arrested rather than rescued. What is clear is that slavery whilst abolished has not stopped. Writing tips on exploratory essays about human trafficking: Exploratory essays ask questions to gather and share information on the topic. It is not necessary to find answers. Introductions for exploratory essays are broad, as you are making an inquiry into a topic, not proving a thesis. Present the topic and the questions you will ask. State your research question clearly state what you want to discover, and why. Identify the issue, its causes and other factors. Identify decision makers and other interested parties. You do not have to supply solutions as the paper is for the purpose of identifying the problem.

Electron Transport Chain and Energy Production

Electron Transport Chain and Energy Production In cellular biology, the electron transport chain is one of the steps in your cells processes that make energy from the foods you eat.   It is the third step of aerobic cellular respiration. Cellular respiration is the term for how your bodys cells make energy from food consumed. The electron transport chain is where most of the energy cells need to operate is generated. This chain is actually a series of protein complexes and electron carrier molecules within the inner membrane of cell mitochondria, also known as the cells powerhouse. Oxygen is required for  aerobic respiration  as the chain terminates with the donation of electrons to oxygen.   Key Takeaways: Electron Transport Chain The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy.Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen. During the passage of electrons, protons are pumped out of the mitochondrial matrix across the inner membrane and into the intermembrane space.The accumulation of protons in the intermembrane space creates an electrochemical gradient that causes protons to flow down the gradient and back into the matrix through ATP synthase. This movement of protons provides the energy for the production of ATP.The electron  transport chain is the third step of aerobic cellular respiration. Glycolysis and the Krebs cycle are the first two steps of cellular respiration. How Energy Is Made As electrons move along a chain, the movement or momentum is used to create  adenosine triphosphate (ATP). ATP is the main source of energy for many cellular processes including muscle contraction and cell division. Adenosine triphosphate (ATP) is a organic chemical that provides energy for cell. ttsz / iStock / Getty Images Plus Energy is released during cell metabolism when ATP is hydrolyzed. This happens when electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen forming water.  ATP chemically decomposes to adenosine diphosphate (ADP) by reacting with water. ADP is in turn used to synthesize ATP. In more detail, as electrons are passed along a chain from protein complex to protein complex, energy is released and hydrogen ions (H) are pumped out of the mitochondrial matrix (compartment within the inner  membrane) and into the intermembrane space (compartment between the inner and outer membranes). All this activity creates both a chemical gradient (difference in solution concentration) and an electrical gradient (difference in charge) across the inner membrane. As more H  ions are pumped into the intermembrane space, the higher concentration of  hydrogen atoms  will build up and flow back to the matrix simultaneously powering the production of ATP by the protein complex ATP synthase. ATP synthase uses the energy generated from the movement of H  ions into the matrix for the conversion of ADP to ATP. This process of oxidizing molecules to generate energy for the production of ATP is called oxidative phosphorylation. The First Steps of Cellular Respiration Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. normaals / iStock / Getty Images Plus The first step of cellular respiration is glycolysis. Glycolysis occurs in the cytoplasm and involves the splitting of one molecule of glucose into two molecules of the chemical compound pyruvate. In all, two molecules of ATP and two molecules of NADH (high energy, electron carrying molecule) are generated. The second step, called the citric acid cycle or Krebs cycle, is when pyruvate is transported across the outer and inner mitochondrial membranes into the mitochondrial matrix. Pyruvate is further oxidized in the Krebs cycle producing two more molecules of ATP, as well as NADH and FADH 2 molecules. Electrons from NADH and FADH2 are transferred to the third step of cellular respiration, the electron transport chain. Protein Complexes in the Chain There are four protein complexes  that are part of the electron transport chain that functions to pass electrons down the chain. A fifth protein complex serves to transport hydrogen ions back into the matrix. These complexes are embedded within the inner mitochondrial membrane.   Illustration of electron transport chain with oxidative phosphorylation. extender01 / iStock / Getty Images Plus Complex I NADH transfers two electrons to Complex I resulting in four H ions being pumped across the inner membrane. NADH is oxidized to NAD, which is recycled back into the Krebs cycle. Electrons are transferred from Complex I to a carrier molecule ubiquinone (Q), which is reduced to ubiquinol (QH2). Ubiquinol carries the electrons to Complex III. Complex II FADH2 transfers electrons to Complex II and the electrons are passed along to ubiquinone (Q). Q is reduced to ubiquinol (QH2), which carries the electrons to Complex III. No H ions are transported to the intermembrane space in this process. Complex III The passage of electrons to Complex III drives the transport of four more H ions across the inner membrane. QH2 is oxidized and electrons are passed to another electron carrier protein cytochrome C. Complex IV Cytochrome C passes electrons to the final protein complex in the chain, Complex IV. Two H ions are pumped across the inner membrane. The electrons are then passed from Complex IV to an oxygen (O2) molecule, causing the molecule to split. The resulting oxygen atoms quickly grab H ions to form two molecules of water. ATP Synthase ATP synthase moves H ions that were pumped out of the matrix by the electron transport chain back into the matrix. The energy from the influx of protons into the matrix is used to generate ATP by the phosphorylation (addition of a phosphate) of ADP. The movement of ions across the selectively permeable mitochondrial membrane and down their electrochemical gradient is called chemiosmosis. NADH generates more ATP than FADH2. For every NADH molecule that is oxidized, 10 H ions are pumped into the intermembrane space. This yields about three ATP molecules. Because FADH2 enters the chain at a later stage (Complex II), only six H ions are transferred to the intermembrane space. This accounts for about two ATP molecules. A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation. Sources Electron Transport in the Energy Cycle of the Cell.

Media kit project Essay Example | Topics and Well Written Essays - 1000 words

Media kit project - Essay Example The main audience in the release is families who are looking for good scenes to spend their happy times, tourists interested in arts and students that are to learn on the historic aspect of art. The main audiences are the ones that the message is designed to reach (Karnes & Shapiro, 2010). Foundation of the museum was by Moody Currier and his third wife and was originally referred to as Currier Gallery of Art. The establishment was to make sure that there was benefit and advancement of humanity. Expansion of the museum has been carried out in different areas where in 2005, there was moving of the offices from the point is located, Kennedy House to Pearl streets (Karnes & Shapiro, 2010). This was due to the first phase of renovation. In construction of the museum in 1867, the place was considered to be the home where several wealth industrials in the city resided. The closing of the museum for renovation was done in 2006, where there was a 21.4 million dollars expansion completed after 21 months in 2008. Additions and renovation that was carried out in the museum lead it to receiving several awards as the people were satisfied with the new face of the museum and more tourists were visiting the area. The awards that were received by the museum were those of Design Honor Award, People’s Choice awards and American Institute of Architects awards. Both the awards were received in 2008 after there was renovation and expansion. This shows that the place has been made a better place where tourists should be able to visit to enjoy the beautiful art scenes, expansion for family vacations and a point in which history is preserved. The museum has incredible exhibition of the work that was carried out by Escher and a permanent collection that is aimed at regional themes and artists. The museum is not so much big but it is well curated
