Question

Quizplus · Accepted Answer

Hydrogen ions (protons) activate ATP synthase by moving from the intermembrane space to the mitochondrial matrix, which drives the synthesis of ATP from ADP and inorganic phosphate. This process is a key part of the chemiosmotic theory, explaining how a proton gradient across the inner mitochondrial membrane is used to generate ATP.
