Oxidative Phosphorylation II: Electron Transport Chain; Respiratory complexes: order and organization, Proton motive force, Chemiosmotic theory
- ETC transfers electrons from NADH/FADH2 to oxygen.
- ETC consist of four unique electron carrier complexes asymmetrically distributed in the inner mitochondrial membrane, each capable of catalyzing electron transfer through a portion of the chain
- Complexes I and II catalyze electrons transfer to ubiquinone from NADH and succinate respectively.
- Complex III carries electrons from reduced ubiquinone to oxidized cytochrome c, and Complex IV completes the sequence by transferring electrons from reduced cytochrome c to O2.
