Organelle connected with lipid synthesis is

Options

A. Ribosome
B. SER
C. Golgi apparatus
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which organelle is connected with lipid synthesis. We need to analyze the options provided: ribosome, smooth endoplasmic reticulum, Golgi apparatus, and all the above.

2. **Analyzing Ribosomes**: Ribosomes are primarily involved in protein synthesis. They are not directly associated with lipid synthesis. Therefore, ribosomes can be eliminated as an answer.

3. **Analyzing Golgi Apparatus**: The Golgi apparatus is involved in the packaging and transport of proteins and lipids but does not directly synthesize lipids. Thus, it is not the correct answer for the question regarding lipid synthesis.

4. **Analyzing Smooth Endoplasmic Reticulum (SER)**: The smooth endoplasmic reticulum is specifically associated with lipid synthesis. It is an interconnected network of flattened membrane-bound sacs and tubules that lack ribosomes. The SER is involved in the production and metabolism of lipids, including the synthesis of steroid hormones and detoxification processes.

5. **Conclusion**: Based on the analysis, the organelle that is directly connected with lipid synthesis is the smooth endoplasmic reticulum. Therefore, the correct answer is option number two: smooth endoplasmic reticulum.
