What is human cytochrome c?


Open in App
Solution

Cytochrome c:

  1. The cytochrome complex, also known as cyt c, is a tiny hemeprotein found loosely attached to the mitochondrion's inner membrane.
  2. It is a member of the cytochrome c protein family and is involved in cell death.
  3. Unlike other cytochromes, cytochrome c is very water-soluble and is a key component of the respiratory electron transport chain, carrying one electron.
  4. It may be oxidized and reduced when its iron atom switches between ferrous and ferric forms, but it does not bind oxygen.
  5. It moves electrons from Complex III (Coenzyme Q – Cyt c reductase) to Complex IV (Coenzyme Q – Cyt c reductase) to Complex IV (Coenzyme Q – Cyt c reductase (Cyt c oxidase).
  6. The CYCS gene is responsible for human cytochrome c production.
