Oxidative phosphorylation - Wikipedia

WebThe last steps of this process occur in the mitochondria. High energy molecules NADH and FADH 2 are generated by the Krebs cycle and glycolysis. These molecules dump electrons onto an electron transport chain to create a proton gradient across the inner mitochondrial membrane. ATP synthase is then used to generate ATP by chemiosmosis. WebApr 28, 2024 · Oxidative Phosphorylation Definition. Oxidative Phosphorylation, also known as OXPHOS, refers to the redox reactions involving the flow of electrons along a series of membrane-bound proteins, coupled with the generation of Adenosine triphosphate (ATP). Oxidative phosphorylation is the fourth and final step in cellular respiration. 北海道観光地ランキング冬
