"Webb4 juli 2024 · Electron Transport Chain. The electron transport chain (aka ETC) is a process in which the NADH and [FADH2] produced during glycolysis, β-oxidation, and other catabolic processes are oxidized thus releasing energy in the form of ATP. The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation. " - Proton biology
