The synthesis of ATP by oxidative phosphorylation,using the energy released by movement of protons across the membrane down their electrochemical gradient,is an example of
A)conversion of potential energy to kinetic energy.
B)an endergonic reaction coupled to an exergonic reaction.
C)a redox reaction.
D)allosteric regulation.

Question

Quizplus · Accepted Answer

Oxidative phosphorylation involves the coupling of the endergonic reaction of ATP synthesis (using energy from the proton gradient) with the exergonic reaction of electron transport chain (which creates the proton gradient). This coupling of reactions is an example of energy transformation from one form to another.
