phosphorylation

 [fos″for-ĭ-la´shun]
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.

ox·i·da·tive phos·phor·y·la·tion

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.

oxidative phosphorylation

n.
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 phosphorylation

The formation of ATP within mitochondria using energy derived from the electron transport chain

ox·i·da·tive phos·phor·y·la·tion

(ok'si-dā'tiv fos'fōr-i-lā'shŭn)
Formation of high energy phosphoric bonds from the energy released by the dehydrogenation (i.e., oxidation) of various substrates.

oxidative phosphorylation

The process of cellular respiration occurring within the MITOCHONDRIA and responsible for the production of adenosine triphosphate (ATP). In this process energy derived from the oxidation of hydrogen, to form water, is transferred to ATP.

oxidative phosphorylation

a process that takes place in the ELECTRON TRANSPORT SYSTEM of aerobic respiration, in which ATP molecules are synthesized from ADP and inorganic phosphate. The process is the major means by which aerobic organisms obtain their energy from foodstuffs.
