Show Answer
Answer:
Correct Answer: D
Solution:
[d] Cytochromes are small proteins (intrinsic membrane proteins) that contain a cofactor, hence, which holds an iron atom.
The iron carries electrons and cycles between + 2 and + oxidation states.
These form a part of electron transport chain in mitochondria and chloroplast and act as an electron transporter or electron acceptor in respiration and photosynthesis.
