Question

Which one of the following enzymes contains 'Heme' as the prosthetic group?

• A. Carbonic anhydrase
• B. Succinate dehydrogenase
• C. Catalase
• D. Rubisco

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.

Answer 1

The Correct Option is C

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.
