Detoxification of harmful drugs is the function of

Options

A. RER
B. SER
C. Lysosome
D. Mitochondria

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the organelle responsible for the detoxification of harmful drugs.

2. **Identifying the Organelles**: The options provided are:
- RER (Rough Endoplasmic Reticulum)
- SER (Smooth Endoplasmic Reticulum)
- Lysosome
- Mitochondria

3. **Analyzing RER**: The Rough Endoplasmic Reticulum (RER) is associated with ribosomes and is primarily involved in protein synthesis. It does not play a significant role in detoxification.

4. **Analyzing SER**: The Smooth Endoplasmic Reticulum (SER) lacks ribosomes and is involved in the synthesis of lipids and the detoxification of harmful drugs. This makes it a strong candidate for the answer.

5. **Analyzing Lysosome**: Lysosomes are known as the "suicidal bags" of the cell, responsible for digesting worn-out organelles and cellular debris, but they are not primarily involved in detoxification of drugs.

6. **Analyzing Mitochondria**: Mitochondria are known as the powerhouse of the cell, primarily responsible for producing ATP through cellular respiration. They do not play a role in detoxification.

7. **Conclusion**: Based on the functions of the organelles, the Smooth Endoplasmic Reticulum (SER) is responsible for the detoxification of harmful drugs.

### Final Answer:
The detoxification of harmful drugs is the function of **Smooth Endoplasmic Reticulum (SER)**.
