Substrate-level phosphorylation

Definition
noun
A type of phosphorylation in which the phosphoryl group is transferred from a donor compound (a phosphorylated reactive intermediate) to the recipient compound
Supplement
Substrate-level phosphorylation is one of the ways in which a phosphate group is introduced into a molecule. Another is oxidative phosphorylation.
In substrate-level phosphorylation, the PO43- from a phosphorylated substrate is transferred to ADP to form ATP. Phosphorylases and kinases catalyse this process. This is what happens during glycolysis in contrast to oxidative phosphorylation involving the electron transport chain and proton motive force.
