Question

Carbonic anhydrase is an example of

• A. Hydrolase enzyme
• B. Redox enzyme
• C. O2 transport protein
• D. Heme protein

Hint:

Hydrolase enzymes catalyze hydrolysis reactions, often involving the addition of water to break bonds. Carbonic anhydrase is a key example in the body.

Answer 1

The Correct Option is A

Step 1: Understanding the enzyme.
Carbonic anhydrase is an enzyme that catalyzes the reversible hydration of carbon dioxide to form carbonic acid. This reaction is a form of hydrolysis, which is why carbonic anhydrase is classified as a hydrolase enzyme.

Step 2: Analyzing the options.
(A) Hydrolase enzyme: Correct — Carbonic anhydrase is a hydrolase enzyme that catalyzes the hydrolysis of CO2.
(B) Redox enzyme: Incorrect — Carbonic anhydrase does not involve oxidation or reduction reactions.
(C) O2 transport protein: Incorrect — Carbonic anhydrase does not transport oxygen. Hemoglobin is an example of an O2 transport protein.
(D) Heme protein: Incorrect — Carbonic anhydrase does not contain a heme group, which is characteristic of hemoglobin or myoglobin.

Step 3: Conclusion.
The correct answer is (A) Hydrolase enzyme as carbonic anhydrase is involved in hydrolysis reactions.
