Question:
Cytochromes, the electron carriers in ETS are __________
Cytochromes, the electron carriers in ETS are __________
Show Hint
Cytochromes carry iron in a haem group.
Updated On: Nov 13, 2026
- Glycoproteins
- Glycolipids
- Sulphur containing proteins
- Iron containing proteins
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Cytochromes are electron carriers in the electron transport system.
Step 2: Nature
They are haem containing proteins, with iron in the haem group that alternates between \(\text{Fe}^{3+}\) and \(\text{Fe}^{2+}\) to carry electrons.
Step 3: Match
So they are iron containing proteins, option (D).
Final Answer:
Cytochromes are iron containing proteins. \[ \boxed{\text{(D) }\text{Iron containing proteins}} \]
