Phospholipid synthetase enzyme occur in :-

Options

A. RER
B. SER
C. Golgibody
D. Glyoxysome

Answer

To determine where the phospholipid synthetase enzyme occurs, we can analyze the options provided step by step.

### Step-by-Step Solution:

1. **Identify the Function of Phospholipid Synthetase:**
- Phospholipid synthetase is an enzyme that is responsible for the synthesis of phospholipids, which are essential components of cell membranes.

2. **Evaluate the First Option: Rough Endoplasmic Reticulum (RER):**
- The rough endoplasmic reticulum is primarily involved in protein synthesis due to the presence of ribosomes on its surface. Therefore, it is not the site for phospholipid synthesis.
- **Conclusion:** RER is not the correct answer.

3. **Evaluate the Second Option: Smooth Endoplasmic Reticulum (SER):**
- The smooth endoplasmic reticulum is involved in the synthesis of lipids, including phospholipids and steroids. This makes it a likely candidate for the location of phospholipid synthetase.
- **Conclusion:** SER is the correct answer.

4. **Evaluate the Third Option: Golgi Body:**
- The Golgi body (or Golgi apparatus) is primarily involved in the packaging and modification of proteins. It does not play a direct role in lipid synthesis.
- **Conclusion:** Golgi body is not the correct answer.

5. **Evaluate the Fourth Option: Glyoxisome:**
- Glyoxisomes are specialized peroxisomes found in plants, primarily involved in the oxidation of fatty acids. They are not involved in the synthesis of phospholipids.
- **Conclusion:** Glyoxisome is not the correct answer.

### Final Answer:
The phospholipid synthetase enzyme occurs in the **Smooth Endoplasmic Reticulum**.
