Question

How can cytochrome c be reduced?

Answer 1

Cytochrome c:

1. Cytochrome complex or cyt - c is a globular protein that is quite small in size.
2. It contains a hemeprotein-iron porphyrin cofactor that is bounded by a polypeptide chain with a covalent bond.
3. Cytochrome c is supremely involved in the electron transport chain which takes place in the inner membrane of mitochondria.

Reduction of cytochrome c:

During the process of cell apoptosis, cytochrome c is reduced by the complex III which is ubiquinol, when the electron transfer takes place through the electron transport chain.
