Which group of organelles is involved in anabolic processes in a cell ?

Options

A. Lysosome, vacuole, ribosome
B. Ribosome, rough ER, smooth ER
C. Vacuole, rough ER, smooth ER
D. Smooth ER, ribosome, vacuole

Answer

**Step-by-Step Solution:**

1. **Understanding Anabolic Processes:**
- Anabolic processes are constructive reactions in which smaller molecules are combined to form larger, more complex molecules. This process requires energy and is considered an endothermic reaction.

2. **Identifying Relevant Organelles:**
- To answer the question, we need to identify which organelles are involved in the synthesis of larger molecules.

3. **Rough Endoplasmic Reticulum (RER):**
- The rough endoplasmic reticulum (RER) is characterized by the presence of ribosomes on its surface. It is primarily involved in the synthesis of proteins. Ribosomes, which are attached to the RER, play a crucial role in translating mRNA into proteins.

4. **Smooth Endoplasmic Reticulum (SER):**
- The smooth endoplasmic reticulum (SER) lacks ribosomes and is involved in the synthesis of lipids. It also plays a role in detoxification and metabolism of carbohydrates, but its primary function in this context is lipid synthesis.

5. **Excluding Other Organelles:**
- **Lysosomes:** These organelles contain hydrolytic enzymes that break down waste materials and cellular debris. They are involved in destructive processes, not anabolic.
- **Vacuoles:** While vacuoles are important for storage (especially in plant cells), they do not directly participate in the synthesis of larger molecules.

6. **Conclusion:**
- The group of organelles involved in anabolic processes in a cell includes the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER), along with ribosomes. Therefore, the answer is: **Ribosomes, Rough ER, and Smooth ER**.
