Question

Cytochrome are

• A. Lipid
• B. Glycoprotein
• C. Metalloporphyrins
• D. $F{e}^{++}$ containing porphyrin pigment

Answer 1

The correct option is D $F{e}^{++}$ containing porphyrin pigment

Cytochromes are iron-containing porphyrin pigment. They are primarily responsible for the generation of ATP via electron transport. They are carrier proteins present in the mitochondria and chloroplasts. These are respiratory pigments. Cytochromes accept and release an electron in electron transport chain.

Thus, the correct answer is option D.
