Question:
Which one of the following enzymes contains 'Heme' as the prosthetic group?
Which one of the following enzymes contains 'Heme' as the prosthetic group?
Show Hint
Heme is a common prosthetic group found in various enzymes involved in oxidation-reduction reactions, such as catalase, which helps in the breakdown of hydrogen peroxide.

- Carbonic anhydrase
- Succinate dehydrogenase
- Catalase
- Rubisco
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Catalase is an enzyme that contains the prosthetic group 'heme'. This group, which contains an iron ion, plays a crucial role in the enzyme’s ability to catalyze the decomposition of hydrogen peroxide into water and oxygen. Heme is also found in other enzymes like peroxidases and cytochromes, but it is most well-known for its role in catalase.
Thus, the correct answer is Catalase.
