HMS uses _____ for removing hydrogen

Options

A. FAD
B. NAD
C. NADP
D. All of these

Answer

To solve the question "HMS uses _____ for removing hydrogen," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question pertains to the process of hydrogen removal in the context of the Hexose Monophosphate Shunt (HMS), also known as the Pentose Phosphate Pathway.

2. **Analyze the Options**: The options provided are:
- FAD
- NAD
- NADP
- All of these options are wrong

3. **Evaluate Each Option**:
- **FAD**: This is a coenzyme that participates in redox reactions, but it is not primarily used for hydrogen removal in the HMS. Thus, this option is incorrect.
- **NAD**: Similar to FAD, NAD is also a coenzyme that accepts electrons and protons, but it is not the main molecule used in the HMS for hydrogen removal. Therefore, this option is also incorrect.
- **NADP**: This is the correct answer. In the Hexose Monophosphate Shunt, NADP (Nicotinamide adenine dinucleotide phosphate) is specifically utilized to remove hydrogen during the oxidation of glucose-6-phosphate.
- **All of these options are wrong**: Since we have identified NADP as the correct answer, this option is incorrect.

4. **Conclusion**: The correct answer to the question is NADP.

### Final Answer:
HMS uses **NADP** for removing hydrogen.
