(b) In chemiosmotic (oxidative) phosphorylation, what is the most direct source of energy that is used to convert ADP + Pi to ATP and what the driving force for the ATP formation through ATP synthase?arrow_forwardA proton gradient is created during the electron transport chain using the energy released from the oxidation of NADH and FADH2. The protons then cross the membrane through ATP synthase down their electrochemical gradient, and ATP is produced. This is an example of A) energy coupling B) cotransport C) allosteric regulation.arrow_forwardExplain the structure and function of ATP synthase.arrow_forward
