The complex carbohydrate form of a sugar that is stored in the liver and muscles is a. glycogen. b. galactose. c. glucagon. d. glucose

a. glycogen.

Explanation:

Glycogen, which is a polymer of glucose residues, is the main reserve polysaccharide in animals and is found in all cells. It is present in greater concentration in the liver and muscle.

Glycogen is important for the production of ATP in muscle cells and in most other cell types. In muscle, energy from glycogen is essential for muscle contraction. In this case, it is noticed that glycogen is not exported, being used by the cell itself. In the liver, glycogen acts as a source of glucose, being responsible for glycemic control. In that case, glucose is exported to other parts of the body.
