Question

The monomer unit of cellulose is .

• A. glucose
• B. amino acid
• C. isoprene

Answer 1

The correct option is A glucose

Cellulose is a natural polymer present in the plant cell walls. They have glucose $\left(C_6{H}_{12}{O}_6\right)$ as its monomer, which forms the repeating unit. These repeating units joined together form the structure of cellulose.

However, amino acid and isoprene are monomers of the polymers- protein and natural rubber respectively.
