Detoxification site in liver is

Options

A. Free ribosomes
B. Golgi complex
C. SER
D. RER

Answer

### Step-by-Step Solution

1. **Understanding the Question**: The question asks for the detoxification site in the liver. We need to identify which cellular structure is primarily responsible for detoxification.

2. **Analyzing the Options**:
- **Free Ribosomes**: These are involved in the synthesis of proteins that are used within the cell. They do not play a role in detoxification.
- **Golgi Complex**: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins. It does not directly participate in detoxification processes.
- **Smooth Endoplasmic Reticulum (SER)**: The SER is involved in various functions, including the detoxification of drugs and poisons, particularly in the liver. This makes it a strong candidate for the detoxification site.
- **Rough Endoplasmic Reticulum (RER)**: The RER is primarily involved in the synthesis of proteins and lipids but does not have a significant role in detoxification.

3. **Identifying the Correct Answer**: Based on the analysis, the Smooth Endoplasmic Reticulum (SER) is the correct answer because it is specifically involved in detoxification processes in the liver.

4. **Conclusion**: The detoxification site in the liver is the Smooth Endoplasmic Reticulum (SER).

### Final Answer
The detoxification site in the liver is the Smooth Endoplasmic Reticulum (SER).
