Find out the wrongly matched pair.

Options

A. Secondary metabolite - Anthocyanin
B. Protein - lnsulin
C. Chitin - polysaccharide
D. Cellulose - Heteropolymer

Answer

To solve the question of finding the wrongly matched pair, we will analyze each option provided in the question systematically.

### Step-by-Step Solution:

1. **Identify the First Pair: Secondary Metabolite - Anthocyanin**
- Anthocyanins are known to be water-soluble pigments found in many plants. They belong to the class of flavonoids, which are indeed secondary metabolites.
- **Conclusion**: This pair is correctly matched.

2. **Identify the Second Pair: Protein - Insulin**
- Insulin is a peptide hormone produced by the pancreas. It is classified as a protein because it is made up of amino acids.
- **Conclusion**: This pair is correctly matched.

3. **Identify the Third Pair: Chitin - Polysaccharide**
- Chitin is a long-chain polymer made up of N-acetylglucosamine units. It is indeed a polysaccharide and is a primary component of the cell walls in fungi.
- **Conclusion**: This pair is correctly matched.

4. **Identify the Fourth Pair: Cellulose - Heteropolymer**
- Cellulose is a polysaccharide that is made up of repeating units of glucose. It is a homopolymer because it consists of only one type of monomer (glucose).
- **Conclusion**: This pair is wrongly matched because cellulose is a homopolymer, not a heteropolymer.

### Final Answer:
The wrongly matched pair is **Cellulose - Heteropolymer**.
