oxidative phosphorylation
(redirected from Oxidative phosphorylation coupling factors)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
phosphorylation /phos·phor·y·la·tion/ (fos-for″ĭ-la´shun) the metabolic process of introducing a phosphate group into an organic molecule.
oxidative phosphorylation  the formation of high-energy phosphate bonds by phosphorylation of ADP to ATP coupled to the transfer of electrons from reduced coenzymes to molecular oxygen via the electron transport chain; it occurs in the mitochondria.
substrate-level phosphorylation  the formation of high-energy phosphate bonds by phosphorylation of ADP to ATP (or GDP to GTP) coupled to cleavage of a high-energy metabolic intermediate.

oxidative phosphorylation
n.
The formation of ATP from the energy released by the oxidation of various substrates, especially the organic acids involved in the Krebs cycle.

oxidative phosphorylation
[ok′sidā′tiv]
an ATP-generating process in which oxygen serves as the final electron acceptor. The process occurs in mitochondria and is the major source of adenosine triphosphate generation in aerobic organisms.

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.

oxidative
pertaining to or emanating from oxidation.

oxidative deamination
oxidative breakdown of amino acids; specialized enzyme systems carry out the process, e.g. d-amino oxidase.
oxidative metabolism
enzymic pathways leading to the addition of oxygen or removal of hydrogen from intermediates in the pathway.
oxidative phosphorylation
the mitochondrial process by which the free energy from the oxidation of intracellular substrates is made available in the form of ATP for cellular endergonic processes.

phosphorylation
the process of introducing a phosphate group into an organic molecule.

oxidative phosphorylation
the final common oxidative pathway in which high-energy phosphate bonds are formed by phosphorylation of ADP to ATP by harnessing by F0,F1-ATPase of the proton motive force generated from pumping of protons from the matrix of mitochondria across the inner mitochondrial membrane to the intermembrance space and is coupled with the transfer of electrons along a chain of carrier proteins with molecular oxygen as the final acceptor.

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