Glycogen is a polymer of ________ molecules.

Question

BlackTom AI · Accepted Answer

Glycogen is a storage polysaccharide in animals, and it is built from repeating glucose units linked primarily by α-1,4-glycosidic bonds with α-1,6 branches. Here, we evaluate the options one by one.
Option 1: starch. While starch is also a polymer of glucose, it is found in plants and serves as their storage polysaccharide. This option confuses the type of organism and storage molecule, making it incorrect for glycogen.
Option 2: glucose. This is the correct monomer for glycogen; each glycosidic linkage connects glucose units. The question asks for the polymer’s monomer, which is glucose.
Option 3: amino acids. Amino acids are the monomers of proteins, not carbohydrates. Since glycogen is a carbohydrate polymer, this choice is inaccurate and reflects a misunderstanding of biomolecule types.
Option 4: fructose. Fructose is another monosaccharide, but glycogen is specifically composed of glucose units, not fructose. This option misidentifies the sugar involved in glycogen.
