Photophosphorylation during photosynthesis differs from oxidative phosphorylation during cellular respiration in that A) it involves an electron transport chain. B) energy is stored in the form of a proton (H⁺) concentration difference. C) generation of ATP is driven by a flow of protons (H⁺) through ATP synthase. D) the final electron acceptor is NADP⁺ and not oxygen.

Question

Quizplus · Accepted Answer

Photophosphorylation during photosynthesis differs from oxidative phosphorylation in cellular respiration mainly in the final electron acceptor used. In photophosphorylation, the final electron acceptor is NADP+ (which becomes NADPH), whereas in oxidative phosphorylation, the final electron acceptor is oxygen (which becomes water).
