Oxidative phosphorylation is a process in which electron are transferred from electron donors to oxygen which acts as electron acceptor. The oxidation-reduction reactions are involved in the formation of a proton gradient. The main role in oxidative phosphorylation is played by the enzyme ATP synthase. This enzyme complex consists of F0 and F1, components. For every two protons passing through F0-F1, complex, synthesis of one ATP molecule takes place.
