The energy source that drives the production of ATP in oxidative phosphorylation is the __________. A) the diffusion of hydrogen protons down their electrochemical gradient B) removal of a phosphate group from ATP C) capture of solar energy D) the production of lactic acid E) the diffusion of CO ₂ across the cell membrane

Question

Quizplus · Accepted Answer

The energy source for ATP production in oxidative phosphorylation is the diffusion of hydrogen protons (H+) down their electrochemical gradient across the inner mitochondrial membrane. This process is facilitated by the enzyme ATP synthase, which uses the energy from the proton gradient to synthesize ATP from ADP and inorganic phosphate.
