Oxidative Phosphorylation

Electron Transport Chain (ETC) and Chemiosmosis.

Series of proteins that transfer electrons from NADH/FADH₂ to oxygen.

H⁺ concentration difference across inner membrane created by ETC.

Enzyme that uses proton flow to synthesize ATP from ADP + Pi.

Oxygen (O₂) forming water after accepting electrons.

Potential energy stored in proton gradient used for ATP production.

~34 ATP from oxidative phosphorylation (≈36 total including glycolysis & CAC).

Substances that dissipate proton gradient, reducing ATP output and producing heat.

Block ETC by binding to complex IV → halts ATP production and cell death.
