This reaction is mostly catalyzed by the enzyme kinases. 4 0 obj Oxidative phosphorylation is the process in which ATP is formed by the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers. Oxidative phosphorylation works by using energy-releasing chemical reactions to drive energy-requiring reactions: The two sets of reactions are said to be coupled.This means one cannot occur without the other. photophosphorylation also produces oxygen (O2) where as oxidative phosphorylation utilizes oxygen Substrate Level Phosphorylation: Substrate level phosphorylation occurs in the glycolysis and Krebs cycle.
