Question

QUESTION 1 What is the purpose of the proton motive force? A Powers the phosphorylation of ATP to ADP. B. Powers the phosphorylation of ADP to ATP. C. Powers the production of high energy electron carriers. D. Powers the ability to generate more redox reactions. 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 or 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 to Complex V (ATP synthase) . To make more ATP from outside sources such as extracellular proteins.

Answer 1

Proton motive force is the force that created by the pumping out of protons across the inner mitochondrial membrane(membrane potential and the gradient of proton concentration).

Proton motive force is mainly used to translocate protons through the ATP synthase complex, leading to the formation of ATP from adenosine diphosphate (ADP) and phosphate.

So, option B is the correct answer.
