• Substrate-level phosphorylation — is a type of chemical reaction that results in the formation of adenosine triphosphate (ATP) by the direct transfer of a phosphate group to adenosine diphosphate (ADP) from a reactive intermediate. In cells, it occurs primarily in the cytoplasm… …   Wikipedia

• Phosphorylation — is the addition of a phosphate (PO4) group to a protein molecule or a small molecule. It can also be thought of as the introduction of a phosphate group into an organic molecule . Its prominent role in biochemistry is the subject of a very large… …   Wikipedia

• Phosphorylation — is a biochemical process that involves the addition of phosphate to an organic compound. Phosphorylation may, for instance, involve the addition of phosphate to glucose to produce glucose monophosphate. Or phosphorylation may, for example,… …   Medical dictionary

• substrate — 1. The substance acted upon and changed by an enzyme; the reactant considered to be attacked in a chemical reaction. 2. The base on which an organism lives or grows; e.g., the s. on which microorganisms and cells grow in cell culture. [L. sub… …   Medical dictionary

• 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, e.g., succinyl CoA in the tricarboxylic acid cycle …   Medical dictionary

• Oxidative phosphorylation — The electron transport chain in the mitochondrion is the site of oxidative phosphorylation in eukaryotes. The NADH and succinate generated in the citric acid cycle are oxidized, releasing energy to power the ATP synthase. Oxidative… …   Wikipedia

• Protein phosphorylation — is a post translational modification of proteins in which a serine, a threonine or a tyrosine reside is covalently modified by a protein kinase enzyme by the addition of a phosphate group. Regulation of proteins by phosphorylation is one of the… …   Wikipedia
