Electron transfer phosphorylation is the process by which electrons are transferred from one molecule to another, and the energy released by this transfer is used to phosphorylate ADP to ATP. In the light-dependent reactions of photosynthesis, electron transfer phosphorylation is used to generate ATP from ADP and inorganic phosphate. The electrons that are transferred come from water, and the energy that is released is used to pump protons across the thylakoid membrane. This creates a proton gradient that drives the synthesis of ATP by ATP synthase.
