Which of the following is not a function Golgi complex ?

Options

A. Biosynthesis of polysaccharides
B. Packaging of proteins
C. Differentiation of cellular membrances
D. Synthesis of fatty acids

Answer

To answer the question "Which of the following is not a function of the Golgi complex?", we will analyze the functions of the Golgi complex step by step.

### Step-by-Step Solution:

1. **Understanding the Golgi Complex**:
- The Golgi complex, also known as the Golgi apparatus, is an essential organelle in eukaryotic cells. It plays a crucial role in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

2. **Identifying Functions of the Golgi Complex**:
- The Golgi complex is involved in several key functions:
- **Formation of Glycoproteins**: The Golgi apparatus modifies proteins by adding carbohydrate groups, forming glycoproteins.
- **Formation of Glycolipids**: Similar to glycoproteins, glycolipids are formed in the Golgi complex by adding carbohydrates to lipids.
- **Packaging of Proteins**: The Golgi complex packages proteins into vesicles for transport to their destinations.
- **Synthesis of Phospholipids**: The Golgi apparatus also plays a role in synthesizing phospholipids.

3. **Analyzing the Options**:
- Now, we need to evaluate the given options (not provided in the transcript, but we can infer based on common knowledge):
- **Biosynthesis of Polysaccharides**: This is generally not a primary function of the Golgi complex; polysaccharides are often synthesized in other organelles like the endoplasmic reticulum (ER).
- **Packaging of Proteins**: This is a well-known function of the Golgi complex.
- **Differentiation of Cellular Membranes**: This is not a specific function attributed to the Golgi complex.
- **Synthesis of Fatty Acids**: Fatty acid synthesis primarily occurs in the cytoplasm and is not a function of the Golgi complex.

4. **Conclusion**:
- Among the options, the differentiation of cellular membranes is not a function of the Golgi complex. Therefore, this is the correct answer to the question.

### Final Answer:
The function that is not associated with the Golgi complex is the **differentiation of cellular membranes**.
