Which is not the fuction of liver

Options

A. production of insulin
B. Detoxifiction
C. Storage of glycogen
D. Production of bile

Answer

To determine which option is not a function of the liver, let's analyze each of the given options step by step.

### Step-by-Step Solution:

1. **Understanding the Functions of the Liver**: The liver is a vital organ with multiple functions, including metabolism, detoxification, and production of various substances.

2. **Evaluating Option 1 - Production of Insulin**:
- Insulin is a hormone that regulates blood glucose levels.
- It is produced by the pancreas, not the liver.
- Therefore, this option does not represent a function of the liver.

3. **Evaluating Option 2 - Detoxification**:
- The liver plays a crucial role in detoxifying harmful substances.
- It converts ammonia (a toxic byproduct of protein metabolism) into urea, which is less toxic and can be excreted by the kidneys.
- Thus, detoxification is indeed a function of the liver.

4. **Evaluating Option 3 - Storage of Glycogen**:
- The liver stores glycogen, which is a polysaccharide form of glucose.
- Glycogen serves as a reserve of energy that can be mobilized when needed.
- Hence, storage of glycogen is a recognized function of the liver.

5. **Evaluating Option 4 - Production of Bile**:
- Bile is produced by the liver and is essential for the digestion and absorption of fats.
- It is stored in the gallbladder and released into the small intestine.
- Therefore, the production of bile is also a function of the liver.

6. **Conclusion**:
- After evaluating all options, it is clear that the only option that is not a function of the liver is the production of insulin, which is performed by the pancreas.

### Final Answer:
The correct answer is **Option 1: Production of Insulin**.
