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 which of the following processes?
A) active transport
B) allosteric regulation
C) a reaction with a positive ΔG
D) coupling of an endergonic reaction to an exergonic reaction

Question

Quizplus · Accepted Answer

The synthesis of ATP by oxidative phosphorylation involves coupling the endergonic process of ATP synthesis to the exergonic process of movement of protons across the membrane down their electrochemical gradient. This process is an example of energy coupling and is essential for the maintenance of cellular energy levels.
