Question

multiple choice question
what is the term used to describe each glucose molecule in a glycogen molecule?

sugar
polymer
polypeptide
monomer

Explanation:

Glycogen is a polysaccharide, and a polysaccharide is made up of repeating monomer units. Glucose is the monomer that polymerizes to form glycogen. A monomer is a small molecule that can join together with other monomers to form a polymer. "Sugar" is a broad term, "polymer" is the large molecule (like glycogen itself), and "polypeptide" is related to proteins (made of amino acids), not carbohydrates like glycogen. So the correct term for each glucose in glycogen is monomer.

Answer:

D. Monomer
