The Golgi complex plays a major role

Options

A. in trapping the light and transforming it into chemical energy.
B. in digesting proteins and carbohydrates.
C. as energy transferring organelles.
D. in post translational modification of proteins and glycosidation of lipids

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of the Golgi Complex**: The Golgi complex is primarily involved in the modification, sorting, and packaging of proteins and lipids that have been synthesized in the cell.

2. **Protein Synthesis**: Proteins are synthesized by ribosomes, which are often attached to the rough endoplasmic reticulum (RER). Once synthesized, these proteins are transported to the Golgi complex for further processing.

3. **Modification of Proteins and Lipids**: In the Golgi complex, proteins undergo post-translational modifications, which may include glycosylation (the addition of sugar molecules). Lipids can also undergo glycosylation in the Golgi.

4. **Evaluating the Options**:
- **Option 1**: Refers to trapping sunlight and transforming it into chemical energy, which is the function of chloroplasts, not the Golgi complex. (Incorrect)
- **Option 2**: Mentions digesting proteins and carbohydrates, which is the role of lysosomes. (Incorrect)
- **Option 3**: States energy transfer, which is the function of mitochondria. (Incorrect)
- **Option 4**: Discusses post-translational modification of proteins and glycosylation of lipids, which accurately describes the role of the Golgi complex. (Correct)

5. **Conclusion**: The Golgi complex plays a major role in the post-translational modification of proteins and glycosylation of lipids, making Option 4 the correct answer.

**Final Answer**: The Golgi complex plays a major role in post-translational modification of proteins and glycosylation of lipids.
