Question:
The enzyme present in RBC is
The enzyme present in RBC is
Show Hint
Remember, Carbonic anhydrase is the key enzyme in RBCs for CO\(_2\) transport and pH buffering.
Updated On: Jun 19, 2026
- Angiotensin
- Renin
- Phosphorylase
- Carbonic anhydrase
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand the role of RBC enzymes.
- Red Blood Cells contain enzymes that facilitate gas transport and maintain pH balance.
Step 2: Identify enzyme options.
- Angiotensin: Hormone involved in blood pressure regulation, not RBC enzyme.
- Renin: Enzyme from kidney, regulates angiotensin system, not in RBC.
- Phosphorylase: Involved in glycogen metabolism, not present in RBC.
- Carbonic anhydrase: Catalyzes conversion of CO\(_2\) + H\(_2\)O ↔ H\(_2\)CO\(_3\), essential for CO\(_2\) transport in RBC
Step 3: Function of carbonic anhydrase in RBC.
- Rapid conversion of CO\(_2\) into bicarbonate in RBCs allows efficient transport of CO\(_2\) from tissues to lungs.
- Maintains acid-base balance in blood.
Step 4: Eliminate incorrect options.
- Angiotensin, Renin, Phosphorylase do not function in RBCs for gas transport.
Step 5: Conclude.
- Therefore, the correct enzyme present in RBC is Carbonic anhydrase.
- Red Blood Cells contain enzymes that facilitate gas transport and maintain pH balance.
Step 2: Identify enzyme options.
- Angiotensin: Hormone involved in blood pressure regulation, not RBC enzyme.
- Renin: Enzyme from kidney, regulates angiotensin system, not in RBC.
- Phosphorylase: Involved in glycogen metabolism, not present in RBC.
- Carbonic anhydrase: Catalyzes conversion of CO\(_2\) + H\(_2\)O ↔ H\(_2\)CO\(_3\), essential for CO\(_2\) transport in RBC

- Maintains acid-base balance in blood.
Step 4: Eliminate incorrect options.
- Angiotensin, Renin, Phosphorylase do not function in RBCs for gas transport.
Step 5: Conclude.
- Therefore, the correct enzyme present in RBC is Carbonic anhydrase.
