phosphorylation

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.

phos·phor·y·la·tion

(fos'fōr-i-lā'shŭn),

Addition of phosphate to an organic compound, such as glucose to produce glucose monophosphate, through the action of a phosphotransferase (phosphorylase) or kinase.

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.

phosphorylation

[fosfôr′ilā′shən]

the process of attaching a phosphate group to a protein, sugar, or other compound.

phos·phor·y·la·tion

(fos'fŏr-i-lā'shŭn)

Addition of phosphate to an organic compound, such as glucose to produce glucose monophosphate, through the action of a phosphotransferase (phosphorylase) or kinase.

phosphorylation

The addition of a phosphate group to an organic molecule.

phosphorylation

the process in which one of more phosphate groups is added to a molecule. Such reactions occur regularly in biological systems. For example, in AEROBIC RESPIRATION glucose is phosphorylated in GLYCOLYSIS; ADP is phosphorylated to ATP at the substrate level and via the ELECTRON TRANSPORT SYSTEM; in plants ATP is produced by PHOTOPHOSPHORYLATION.

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.
