NAD, FAD: transport H ions and electrons into oxidative phosphorylation reaction A sequence of membrane proteins arranged in order of increasing redox potential; operated by NADH and FADH. Electrons move down the redox gradient and the resulting energy is used to pump H+ ions out of the inner mitochondrial membrane. Purpose is to build a negative charge inside membrane and thus attract H+ ions back into the mitochondrion. (the membrane is impervious to H+ except for proton channels; therefore the protons have no choice but to operate the ATPase enzyme) Oxidative Phosphorylation: RAW MATERIALS: ADP, Inorganic Phosphate, Oxygen. The conversion of ADP and inorganic phosphate into ATP. This is done by Protontranslocating ATPase. This enzyme is activated by the passage of H+ ions into the mitochondrion though a proton channel to which the ATPase is linked. 3 H+ ions for 1 ATP molecule
