- The cytochrome chain is a part of the Electron Transport Chain. It is a multi-enzyme system found in the inner membrane of the mitochondria.
- The ETP is the final part of cellular respiration and is the only part that uses oxygen from the atmosphere. Oxygen is the last electron receptor in the chain.
- The cytochrome chain’s role is to transfer electrons. It uses electrons from electron carriers in order to form a chemical gradient. This is used for the process of oxidative phosphorylation.
- Electrons from both NADH and FADH2 are passed through the gradient toward oxygen, which is then reduced to H2O.
