oxidative phosphorylation(redirected from Oxidative phosphorylization)
Also found in: Dictionary, Thesaurus, Encyclopedia.
the process of introducing a phosphate group into an organic molecule.
oxidative phosphorylation the final common pathway of aerobic energy metabolism in which high-energy phosphate bonds are formed by phosphorylation of ADP to ATP coupled with the transfer of electrons along a chain of carrier proteins with molecular oxygen as the final acceptor. It occurs in mitochondria.
formation of high-energy phosphoric bonds (for example, in pyrophosphates) from the energy released by the flow of electrons to O2 and the dehydrogenation (i.e., oxidation) of various substrates, most notably isocitric acid, α-ketoglutaric acid, succinic acid, and malic acid in the tricarboxylic acid cycle.
The process in cell metabolism by which respiratory enzymes in the mitochondria synthesize ATP from ADP and inorganic phosphate during the oxidation of NADH by molecular oxygen.
oxidative phosphorylationThe formation of ATP within mitochondria using energy derived from the electron transport chain
