- Cellulose: Cellulose is a polysaccharide found in plants, not in animals. It is the structural component of plant cell walls.
- Starch: Starch is a polysaccharide found in plants, primarily used by plants to store energy.
- Glycogen: This is the correct answer. Glycogen is the primary storage form of carbohydrates in animals, primarily stored in the liver and muscles. It can be broken down into glucose when needed by the body for energy.
- Amylopectin: This is a component of starch, not a storage form of carbohydrates in animals.
- Amylase: Amylase is an enzyme that breaks down carbohydrates, not a carbohydrate storage molecule.
Thus, the correct answer is (C) glycogen.
