The electron transport, which occurs at the inner membrane of the mitochondrion and leads to the synthesis of ATP, results in which of the following processes?

Question

Quizplus · Accepted Answer

During the electron transport chain, electrons are passed along a series of protein complexes in the inner membrane of the mitochondrion. As they move along the chain, the complexes pump protons from the matrix of the mitochondrion into the intermembrane space, creating a gradient of protons. This gradient is then used by ATP synthase to generate ATP through oxidative phosphorylation. Therefore, the correct answer is A: pumping of protons from the matrix of the mitochondrion to the intermembrane space.
