Hello. This question is incomplete. The full question is:

"Glycogen is an energy-storage molecule in humans. A hormone that is called insulin controls the storage of glycogen in the liver. Insulin is made up of amino acids.  Which statement correctly identifies the types of macromolecules that are described?"

Glycogen is a carbohydrate, and insulin is a protein

Explanation:

Glycogen is the main reserve carbohydrate in animals, just as starch is in plants. It is a polymer formed by glucose residues joined by glycosidic bonds. It is estimated that a glycogen molecule contains about 60,000 glucose residues.

Insulin is a protein with two linked polypeptide chains, containing 21 amino acids in chain A and 30 amino acids in chain B. The chains are linked by disulfide bonds. There are several types of insulin stimulus and secretion by β cells of the pancreas.
