During oxidative phosphorylation, the energy needed to drive ATP synthesis comes from one source. Which of the following statements states the immediate source of that energy?

During oxidative phosphorylation, the energy needed to drive ATP synthesis comes from one source. Which of the following statements states the immediate source of that energy? Correct Answer The proton gradient across the membrane where the ATP synthase is embedded represents potential energy.

(D) Protons flowing down a gradient through ATP synthase provide energy to phosphorylate ADP into ATP. Energy from the exergonic flow of electrons to oxygen provides the energy to pump protons across the cristae membrane and form a gradient.
