The hexose monophosphate shunt is also called

Options

A. EMP pathway
B. HMS pathway
C. TCA pathway
D. Citric acid cycle

Answer

### Step-by-Step Solution:

1. **Understanding the Term "Hexose Monophosphate Shunt":**
- The term "shunt" refers to a pathway that bypasses a series of reactions. In this case, the hexose monophosphate shunt is a metabolic pathway that diverts glucose-6-phosphate from glycolysis.

2. **Identifying the Other Name:**
- The hexose monophosphate shunt is also known as the **Pentose Phosphate Pathway (PPP)**. This pathway is crucial for producing NADPH and ribose-5-phosphate, which are essential for anabolic reactions.

3. **Differentiating from Other Pathways:**
- The question mentions several pathways: EMP pathway (glycolysis), TCA pathway (Krebs cycle), and HMS pathway.
- The EMP pathway is specifically glycolysis, which is not the same as the hexose monophosphate shunt.
- The TCA pathway refers to the citric acid cycle, which is also distinct from the hexose monophosphate shunt.

4. **Conclusion:**
- Therefore, the hexose monophosphate shunt is primarily referred to as the **Pentose Phosphate Pathway (PPP)**.

### Final Answer:
The hexose monophosphate shunt is also called the **Pentose Phosphate Pathway (PPP)**.
