20.1 - Where in the Cell Are<br />
<strong>Electron</strong> <strong>Transport</strong> <strong>and</strong> <strong>Oxidative</strong><br />
<strong>Phosphorylation</strong> Carried Out?<br />
• <strong>Electron</strong> <strong>Transport</strong>: <strong>Electron</strong>s carried by<br />
reduced coenzymes are passed through a chain<br />
of proteins <strong>and</strong> coenzymes to drive the<br />
generation of a proton gradient across the inner<br />
mitochondrial membrane<br />
• <strong>Oxidative</strong> <strong>Phosphorylation</strong>: The proton gradient<br />
runs downhill to drive the synthesis of ATP<br />
• It all happens in or at the inner mitochondrial<br />
membrane
