Vitamin `B_(2)` is component of coenzyme

Options

A. Pyridoxal phosphate
B. TPP
C. NAD
D. FMN/FAD.

Answer

To solve the question "Vitamin B2 is a component of coenzyme," we need to identify which coenzyme contains Vitamin B2 (also known as riboflavin). Let's analyze the options given one by one.

### Step-by-Step Solution:

1. **Identify Vitamin B2**:
- Vitamin B2 is also known as riboflavin. It is important to know this before we look at the options.

2. **Analyze the Options**:
- **Option A: Pyridoxal phosphate**:
- This coenzyme is derived from Vitamin B6, which is pyridoxin. Therefore, this option is incorrect.

- **Option B: Thiamine pyrophosphate (TPP)**:
- This coenzyme is derived from Vitamin B1, which is thiamine. Thus, this option is also incorrect.

- **Option C: NAD (Nicotinamide adenine dinucleotide)**:
- This coenzyme is derived from Vitamin B3, which is niacin. Hence, this option is incorrect as well.

- **Option D: FMN (Flavin mononucleotide) and FAD (Flavin adenine dinucleotide)**:
- Both of these coenzymes are derived from Vitamin B2, which is riboflavin. Therefore, this option is correct.

3. **Conclusion**:
- The correct answer is **Option D**: FMN and FAD, as they are the coenzymes that contain Vitamin B2 (riboflavin).

### Final Answer:
Vitamin B2 is a component of coenzymes FMN and FAD.
