Vitamin `B_(2)` is involved in formation of coezyme

Options

A. NAD,NADP
B. FMN,FAD,
C. NAN,FAD
D. NADP,FMN

Answer

To solve the question about which coenzymes vitamin B2 (riboflavin) is involved in forming, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Vitamin B2**:
- Vitamin B2 is also known as riboflavin. It is a water-soluble vitamin that plays a crucial role in various biological processes.

**Hint**: Remember that riboflavin is the scientific name for vitamin B2.

2. **Understand the Role of Riboflavin**:
- Riboflavin is essential for the formation of certain coenzymes in the body. Coenzymes are non-protein compounds that are necessary for the functioning of enzymes.

**Hint**: Coenzymes assist enzymes in catalyzing biochemical reactions.

3. **Identify the Coenzymes Associated with Riboflavin**:
- The two main coenzymes formed from riboflavin are:
- FMN (Flavin Mononucleotide)
- FAD (Flavin Adenine Dinucleotide)

**Hint**: Focus on the names of the coenzymes; they both contain "flavin," indicating their connection to riboflavin.

4. **Evaluate the Options Provided**:
- The options given in the question are:
1. NAD and NADP
2. FMN and FAD
3. NAN and FAD
4. NADP and FMN
- From our understanding, we know that riboflavin is specifically involved in the formation of FMN and FAD.

**Hint**: Cross-check the options with the coenzymes you identified.

5. **Select the Correct Option**:
- Based on the information, the correct option is:
- **Option 2: FMN and FAD**

**Hint**: Always confirm your answer by recalling the specific functions of the vitamin in question.

### Conclusion:
Vitamin B2 (riboflavin) is involved in the formation of the coenzymes FMN (Flavin Mononucleotide) and FAD (Flavin Adenine Dinucleotide). Therefore, the correct answer is option 2.
