Electron Transport Chain

12. Briefly discuss the role of the electron transport chain in cellular respiration. In your explanation, discuss and identify key molecules involved in this process and explain their relationship which each other in terms of how they contribute to the main cellular purpose of this process. Electron transport chain plays a key role of in the production of oxygen in cellular respiration. ETC uses many enzymes located on the inner mitochondrial membrane during the production of oxygen. The source of these electrons are NADH and FADH2 which are the key molecules in this process and as these electrons are passed along this series of enzymes, they give up energy which is used to carry out chemiosmosis by which H+ ions are actively transported across the inner mitochondrial membrane into the outer mitochondrial compartment. Next, the H+ ions then flow back through special pores in the membrane, and the process is thought to drive the process of ATP synthesis. One glucose molecule produces the net yield of 34 ATP and consequently 6 H2O molecules are formed when these electrons unite with molecular O2 at the end of electron transport chain.
13. Explain naturally-occuring human chimerism. How could it occur, and why is important for the general public to be aware
Some choose to be vegetarian while others prefer to have a high protein diet (i.e. animal products). Proteins are necessary to every human for growth, so the vegetarian people who consume vitamins sources should look for protein sources as well within the vegetable sources. On the other hand the non-vegetarian people get both protein and vitamin nutrients. The vegetarian people should have fresh fruit juices, oats, green leafy vegetables and so on. Soyabean is a good alternative of meat and fish. Pulses too contain high protein percentage. So, it is upto the people to select the food habit for a healthy
