If 15 Acetyl CoA enter in to Krebs cycle then how many `CO_(2)` molecules are produced after complete decarboxylation:

Options

A. `60 CO_(2)` molecule
B. `15 CO_(2)` molecule
C. `30 CO_(2)` molecule
D. `75 CO_(2)` molecule

Answer

To solve the question of how many CO₂ molecules are produced when 15 Acetyl CoA enter the Krebs cycle, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Acetyl CoA in the Krebs Cycle**:
- Acetyl CoA is a two-carbon molecule that enters the Krebs cycle.

2. **Know the Decarboxylation Process**:
- During each turn of the Krebs cycle, one Acetyl CoA molecule leads to the release of 2 molecules of carbon dioxide (CO₂) through decarboxylation.

3. **Calculate CO₂ Production for One Acetyl CoA**:
- For 1 Acetyl CoA, the number of CO₂ produced = 2 CO₂.

4. **Calculate CO₂ Production for 15 Acetyl CoA**:
- If 15 Acetyl CoA enter the Krebs cycle, the total CO₂ produced can be calculated as:
\[ \text{Total CO₂} = \text{Number of Acetyl CoA} \times \text{CO₂ produced per Acetyl CoA} \]
\[ \text{Total CO₂} = 15 \times 2 = 30 \text{ CO₂} \]

5. **Conclusion**:
- Therefore, when 15 Acetyl CoA molecules enter the Krebs cycle, a total of 30 CO₂ molecules are produced after complete decarboxylation.

### Final Answer:
- The answer is **30 CO₂ molecules**.
