Which of the following polymers of glucose is stored by animals?

Options

A. Cellulose
B. Amylose
C. Amylopectin
D. Glycogen

Explanation

To determine which polymer of glucose is stored by animals, we will analyze each of the given options one by one.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- 1. Cellulose
- 2. Amylose
- 3. Amylopectin
- 4. Glycogen

2. **Analyze Cellulose**:
- Cellulose is a polymer of glucose but is primarily found in plants. It serves as a structural component in plant cell walls.
- **Conclusion**: Cellulose is not stored by animals.

3. **Analyze Amylose**:
- Amylose is a component of starch, which is a storage form of glucose in plants. It is a linear polymer of glucose units.
- **Conclusion**: Amylose is not stored by animals.

4. **Analyze Amylopectin**:
- Amylopectin is another component of starch, alongside amylose. It is a branched polymer of glucose and is also found in plants.
- **Conclusion**: Amylopectin is not stored by animals.

5. **Analyze Glycogen**:
- Glycogen is a highly branched polymer of glucose and serves as the primary storage form of glucose in animals. It is mainly stored in the liver and muscle tissues.
- **Conclusion**: Glycogen is the polymer of glucose that is stored by animals.

6. **Final Answer**:
- Based on the analysis, the polymer of glucose that is stored by animals is **option 4: Glycogen**.
