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

Options

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

Explanation

To solve the question "Which of the following polymers of glucose is stored by animals?", we will analyze the provided options step by step.

### Step 1: Identify the options
The options given are:
1. Cellulose
2. Amylose
3. Amylopectin
4. Glycogen

### Step 2: Analyze each option
- **Cellulose**: This is a major structural polysaccharide found in plants, primarily in the cell wall. It is not used for energy storage in animals.

- **Amylose**: This is a linear polymer of alpha-glucose and is part of starch. While it is a storage form of glucose in plants, it is not stored in animals.

- **Amylopectin**: This is a branched polymer of alpha-glucose and is also part of starch. Like amylose, it serves as a storage form of glucose in plants, not in animals.

- **Glycogen**: This is a highly branched polymer of glucose that serves as the primary storage form of glucose in animals. It is mainly found in the liver and muscle tissues and is often referred to as "animal starch."

### Step 3: Conclusion
From the analysis, it is clear that the correct answer is **Glycogen**, as it is the polymer of glucose that is stored by animals.

### Final Answer:
**Glycogen** is the polymer of glucose that is stored by animals.
