- electron transport chain
- the series of electron carriers in the inner mitochondrial membrane that pass electrons from reduced coenzymes (NADH, FADH2) to molecular oxygen via sequential redox reactions coupled to vectorial transduction of protons across the membrane. The chain is the final common pathway of biological oxidation, using O2 for fuel combustion; the energy produced is utilized for ATP synthesis, ion translocation, and protein synthesis. See illustration. Called also respiratory c. See also oxidative phosphorylation.
