Oxidative Phosphorylation
Oxidative phosphorylation
Mitochondrial ATP production driven by electron transport and a proton gradient across the inner membrane.
Overview
EXPLORE BY LEVELIn Cell structures that help release energy from nutrients and perform other essential jobs., electrons move through a chain of protein complexes. The chain helps build a difference in proton concentration across a membrane, and A membrane protein complex that uses a proton gradient to make ATP. uses that stored energy to make ATP.

Oxidative phosphorylation couples redox free-energy changes to proton-motive force and ATP synthesis. Coupling efficiency, leak, transport costs, and tissue-specific respiratory capacity affect ATP yield.
