As electrons move through the mitochondrial space,

Question

Quizplus · Accepted Answer

As electrons move through the mitochondrial space, they create a proton gradient across the inner mitochondrial membrane, causing the pH of the intermembrane space to decrease. This proton gradient is then used by ATP synthase to generate ATP. NADH is reduced and water is oxidized earlier in the electron transport chain, but this is not directly related to the movement of electrons through the mitochondrial space. Active transport is also not involved in ATP synthase, which uses the proton gradient to drive ATP synthesis through passive transport.
