In what physical form the glycogen is found in cells

Options

A. Liquid
B. Soluble
C. Crystallized
D. Insoluble

Answer

### Step-by-Step Solution

1. **Understanding Glycogen**: Glycogen is a polysaccharide that serves as a form of energy storage in animals and humans. It is composed of glucose units linked together.

2. **Location of Glycogen**: Glycogen is primarily stored in the liver and muscle cells of animals and humans.

3. **Physical State of Glycogen**: The question asks about the physical form of glycogen in cells. We need to evaluate the options provided: liquid, soluble, crystallized, and insoluble.

4. **Evaluating Options**:
- **Liquid**: Glycogen is not found in a liquid state within cells.
- **Soluble**: Glycogen is not soluble in water; it does not dissolve easily.
- **Crystallized**: While glycogen can form granules, it is not typically referred to as crystallized in a strict sense.
- **Insoluble**: Glycogen is considered insoluble in nature, meaning it does not dissolve in water and exists as granules within the cells.

5. **Conclusion**: Based on the analysis, the correct answer to the question is that glycogen is found in an **insoluble** physical form in cells.

### Final Answer
Glycogen is found in cells in an **insoluble** physical form.
