Which of the following is mismatched ?

Options

A. Chitin`" "`-`" "`Polymer of glucosamine
B. Glycogen`" "`-`"
"`Polymer of glucose
C. Cellulose`" "`-`" "`Heteropolysaccharide
D. Inulin`" "`-`" "`Homopolysaccharide

Answer

To determine which of the following options is mismatched, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option 1: Chitin, polymer of glucosamine**
- Chitin is indeed a polymer made up of glucosamine units. It is found in the cell walls of fungi and the exoskeletons of arthropods.
- **Conclusion**: This option is correct.

2. **Option 2: Glycogen, polymer of glucose**
- Glycogen is a polysaccharide that serves as a form of energy storage in animals and fungi. It is composed of glucose units linked together.
- **Conclusion**: This option is correct.

3. **Option 3: Cellulose, heteropolysaccharide**
- Cellulose is a homopolysaccharide made up of β-glucose units. It is a major component of the cell wall in plants. Therefore, stating that cellulose is a heteropolysaccharide is incorrect.
- **Conclusion**: This option is a mismatch.

4. **Option 4: Inulin, homopolysaccharide**
- Inulin is a homopolysaccharide composed of fructose units. It is found in various plants, particularly in the roots of certain plants like chicory.
- **Conclusion**: This option is correct.

### Final Answer:
The mismatched option is **Option 3: Cellulose, heteropolysaccharide**.
