The polysaccharide present in the exoskeletons of arthropods is

Options

A. Hyaluronic acid
B. Chitin
C. Cellulose
D. Glycogen

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the polysaccharide found in the exoskeletons of arthropods.

2. **Identifying Polysaccharides**: Polysaccharides are complex carbohydrates that can be classified into different categories, including storage polysaccharides and structural polysaccharides.

3. **Types of Polysaccharides**:
- **Storage Polysaccharides**: Examples include starch (found in plants) and glycogen (found in animals).
- **Structural Polysaccharides**: These include cellulose (found in plant cell walls) and chitin (found in the exoskeletons of arthropods and in fungal cell walls).

4. **Focusing on Arthropods**: Since the question specifically mentions arthropods, we need to identify the structural polysaccharide that is relevant to them.

5. **Identifying the Correct Polysaccharide**: The polysaccharide that forms the exoskeleton of arthropods is chitin. Chitin is a complex carbohydrate that is a homopolymer made up of N-acetylglucosamine (NAG) units.

6. **Conclusion**: Therefore, the correct answer to the question is chitin.

**Final Answer**: The polysaccharide present in the exoskeletons of arthropods is **chitin**.
