Cytochrome is

  1. metallo flavo protein
  2. Fe containing porphyrin pigment
  3. glycoprotein
  4. lipid.

Answer

(2) Fe containing porphyrin pigment

Solution

As per NCERT, cytochromes (cytochrome b, c, a, a3) are electron carriers of the electron transport system in the inner mitochondrial membrane.

⇒ Each cytochrome is a haem protein: its prosthetic group is a porphyrin ring holding an iron atom that changes between Fe3+ and Fe2+ while carrying electrons.

∴ Cytochrome is an Fe containing porphyrin pigment.
