The return of the protons into the mitochondrial matrix through mitochondrial membrane channels occurs by the process of _________.

Question

Quizplus · Accepted Answer

The return of protons through the mitochondrial membrane channels occurs by the process of diffusion, as the high concentration of protons in the intermembrane space diffuses to the lower concentration in the mitochondrial matrix. Osmosis is the movement of water molecules across a semi-permeable membrane, and active transport involves the movement of molecules against their concentration gradient via the use of energy. Reversal of potential is not a process that occurs during proton movement in mitochondria.
