Mitochondrial Electron Transport Efficiency

Meaning

Mitochondrial Electron Transport Efficiency is a measure of how effectively the electron transport chain (ETC) within the inner mitochondrial membrane converts the energy from reducing equivalents (NADH and FADH₂) into a proton gradient, which subsequently drives Adenosine Triphosphate (ATP) synthesis. High efficiency means more ATP is produced per unit of oxygen consumed, indicating minimal electron leakage and reduced reactive oxygen species generation. This metric is a core determinant of cellular energy status and systemic vitality.
