Question

How many cytochromes are there?

Answer 1

Cytochromes:

1. Redox-active proteins known as cytochromes include a heme, which has a central Fe atom at its center, as a cofactor.
2. They take part in the electron transport chain and redox catalysis.
3. They are categorized based on the type of heme and how it binds.
4. a, b, and c are the three classes of cytochromes according to their light-absorption spectra.
5. There are at least 30 distinct cytochromes known, and they are identified by letters or letter-number combinations, such as cytochrome a₃, cytochrome c, and cytochrome B562.
