The Electron Transport Chain: Complex III

The video tutorial explains the physiology and mechanism of Complex III in the mitochondrial respiratory chain. It covers the enzyme's various names, its role in electron transfer from ubiquinol to cytochrome C, and the Q cycle. The tutorial also discusses the enzyme's ability to pump protons across the membrane, contributing to the proton gradient. The net reaction involves the transfer of electrons from ubiquinol to cytochrome C, which then moves to cytochrome C oxidase.
