Question 5 (Mandatory) (6 points) In the electron transport chain, electrons are transferred from Complexes I and II to Complex Ill via N The electrons from Complex III are transferred to Complex IV via O₂ is reduced to H₂0 at Complex N W A Question 6 (Mandatory) (9 points) You examine respiration in a preparation of freshly-isolated mitochondria in aerobic condition. (A) When you add ADP, Pi, and succinate to the solution containing mitochondria, what would happen to O₂ consumption and ATP synthesis? Explain. (B) How O₂ consumption and ATP synthesis change from (A) upon adding oligomycin, which inhibits ATP synthase? Explain. (C) How O₂ consumption and ATP synthesis change from (B) upon adding an uncoupler? Explain.
Question 13 (Mandatory) (6 points) Match the following. amino group carrier in muscle intracellular amino group carrier intercellular amino group carrier 1. glutamate 2. glutamine 3. alanine Question 14 (Mandatory) (10 points) A person with a defective argininosuccinase will exhibit high levels of ammonia. Without argininosuccinase, ornithine won't be generated in sufficient quantities to react with all the carbamoyl phosphate, which will "back up" that reaction and lead to an increase in ammonia. This could lead to coma or death if left untreated. (A) Which reaction does argininosuccinase carry out? (3 pts) 3) Treatment of this condition involves administering large amounts of arginine orally. Upon administration of arginine, increased levels of are found in the urine (think about what would build up with this enzymatic deficiency and lots of arginine) (3 pts) (C) Explain how taking arginine pills allows for the excretion of 2 nitrogens generated from protein breakdown in the cell (nitrogen that did not originate with the arginine given orally.) Limit to 100 words.(4 pts)
