please help!! 37. What is the name of the enzyme that creates ATP in oxidative phosphorylation?...
Which of the following could explain why transfer of electrons from FADH2 to Coenzyme Q (CoQ) is not coupled to proton transfer, but transfer from NADH to Coenzyme Q is? Select one: a. FADH2 donates more electrons than NADH to the electron transport chain. b. Because FADH2 has higher affinity for electrons than Coenzyme Q c. Because FADH2 is a higher energy carrier than NADH d. Because the transfer of electrons from FADH2 to CoQ does not release enough energy....

QUESTION 2 What is the main mechanism of action for oxidative phosphorylation? A Uses the free energy of the proton gradient generated as a result of transferring electrons from NADH OF FADH2 to O2 by a series of electron carriers for ATP production B. Uses the net yield of ATP produced by Glycolysis and the Citric Acid Cycle to produce more ATP. Uses the free energy released during redox reactions in Complexes I-IV (the electron transport chain) and is uncoupled...
