What is the substrate for HMS

Options

A. Fructose
B. Glucose
C. Sucrose
D. Starch

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the substrate of the Hexose Monophosphate Shunt (HMS). The HMS is a metabolic pathway that involves the oxidation of glucose-6-phosphate.

2. **Analyzing the Options**:
- **Option 1: Fructose**: This is a sugar found in fruits and is absorbed directly into the bloodstream. It is not the substrate for HMS.
- **Option 2: Glucose**: This is the correct answer. Glucose is converted into glucose-6-phosphate, which is the substrate for the HMS.
- **Option 3: Sucrose**: This is a disaccharide made up of glucose and fructose. It is not directly involved as a substrate in the HMS.
- **Option 4: Starch**: This is a polysaccharide that serves as energy storage in plants. It is not the substrate for HMS.

3. **Conclusion**: The substrate for the Hexose Monophosphate Shunt is **glucose**.

### Final Answer:
The substrate for the Hexose Monophosphate Shunt (HMS) is **glucose**.
