Glycogen is stored in

Options

A. liver and muscles
B. liver only
C. muscles only
D. pancreas

Answer

**Step-by-Step Solution:**

1. **Understanding Glycogen**: Glycogen is a polysaccharide that serves as a form of energy storage in animals. It is primarily made up of glucose units.

2. **Role of Insulin**: When we consume food, glucose is released into the bloodstream. The pancreas secretes insulin, a hormone that helps regulate blood sugar levels.

3. **Glucose Absorption**: After eating, glucose is absorbed from the small intestine into the bloodstream. This glucose is used by the body for immediate energy needs.

4. **Storage of Excess Glucose**: Any excess glucose that is not immediately needed for energy is converted into glycogen for storage.

5. **Locations of Glycogen Storage**: The primary sites for glycogen storage in the body are:
- **Liver**: The liver stores glycogen and can release glucose back into the bloodstream when needed.
- **Muscles**: Skeletal muscles also store glycogen, which is used locally for energy during physical activity.

6. **Conclusion**: Therefore, glycogen is stored in both the liver and muscles.

**Final Answer**: Glycogen is stored in the liver and muscles.
