![During the process of oxidative phosphorylation the electron transport chain couples the
movement of electrons to the pumping of protons (H+) into the intermembrane space of
the mitochondria (left side of graphic below). This reaction establishes a protonmotive
force that can then be utilized to synthesize ATP by a molecular machine called the
ATP-synthase (right side of graphic). ATP-synthase is an integral membrane protein
found within the inner mitochondrial membrane. The pH of the mitochondrial matrix
(inside) is ~ 7.8, whereas the pH of the intermembrane space of the mitochondria
(outside) is ~7.1.
