The electron transport chain is triggered by the transfer of high-energy electrons from NADH and FADH2, which are generated during glycolysis and the citric acid cycle.

How does oxidative phosphorylation differ from glycolysis?

  • Biologists and chemists interested in the molecular mechanisms of energy production
  • How Does Oxidative Phosphorylation Work?

  • Oxidative phosphorylation is only relevant for muscle cells: Incorrect, as it is a ubiquitous process essential for all cells.
  • At the heart of oxidative phosphorylation lies the electron transport chain, a series of protein complexes embedded in the mitochondrial inner membrane. During this process, high-energy electrons are passed along a series of electron carriers, resulting in the generation of a proton gradient across the membrane. This gradient, in turn, drives the production of ATP (adenosine triphosphate), the primary energy currency of the cell.
