Electron Transport Chain

Electron Transport Chain Definition The Electron Transport System also called the Electron Transport Chain, is a chain of reactions that converts redox energy available from oxidation of NADH and FADH2, into proton-motive force which is used to synthesize ATP through conformational changes in the ATP synthase complex through a process called oxidative phosphorylation. Oxidative phosphorylation is the last step of cellular respiration. This stage consists of a series of electron transfer from organic compounds to oxygen while simultaneously releasing energy … Read more

Electron Transport Chain (ETC)- Components and Steps

The NADH and FADH2 formed in glycolysis, TCA cycle and fatty acid oxidation are energy-rich molecules because they contain a pair of electrons that have high transfer potential. ATP is generated as a result of the energy produced when electrons from NADH and FADH2 are passed to molecular oxygen by a series of electron carriers, collectively known as the electron transport chain (ETC). The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The … Read more
