Enzyme involved in `CO_(2)` transport in blood is

Options

A. carboxylase
B. carboxykinase
C. carbonic anhydrase
D. none of these

Answer

To solve the question regarding the enzyme involved in CO₂ transport in blood, we can follow these steps:

### Step 1: Understand the Context of CO₂ Transport
CO₂ is a waste product produced by cellular respiration and needs to be transported from the tissues to the lungs for exhalation.

### Step 2: Identify the Mechanism of CO₂ Transport
CO₂ is primarily transported in the blood in three forms:
1. Dissolved in plasma
2. Bound to hemoglobin as carbamino compounds
3. As bicarbonate ions (HCO₃⁻) formed in red blood cells.

### Step 3: Focus on the Role of Enzymes
The conversion of CO₂ into bicarbonate ions involves a specific enzyme that catalyzes the reaction between CO₂ and water (H₂O).

### Step 4: Identify the Correct Enzyme
The enzyme that catalyzes the reaction of CO₂ with water to form carbonic acid (H₂CO₃), which then dissociates into bicarbonate (HCO₃⁻) and hydrogen ions (H⁺), is known as **carbonic anhydrase**.

### Step 5: Conclusion
Based on the information and the options provided, the correct answer to the question is **option C: carbonic anhydrase**.

### Final Answer
The enzyme involved in CO₂ transport in blood is **carbonic anhydrase**.
