An electron transport chain (ETC) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane.

Electron Transport Chain Definition. The electron transport chain is a cluster of proteins that transfer electrons through a membrane to create a gradient of protons that creates ATP (adenosine triphosphate) or energy that is needed in metabolic processes for cellular function.

Now every time an electron goes from a higher energy state to a lower energy state-- and that's what it's doing over the course of this electron transport chain-- it's releasing energy. So energy is released when you go from a higher state to a lower state.

Where the Electron Transport Chain Is Located Electron transport requires a membrane in order to work. In prokaryotic cells , those of bacteria and bacteria-like Archaeans, electron transport takes place in the cell’s plasma membrane, in folded areas called mesosomes.

The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.

The electron transport chain is a mitochondrial pathway in which electrons move across a redox span of 1.1 V from NAD+/NADH to O 2 /H 2 O. Three complexes are involved in this chain, namely, complex I, complex III, and complex IV.

The Protein Complexes of the Electron Transport Chain Many years of effort have been devoted to the study of the remarkable processes in the mitochondria . The electron transport chain is the final stage of aerobic respiration leading to the forming of ATP in the inner membrane of the mitochondrion.
