Answer
Glycogen is indeed a polysaccharide, primarily found in animal cells. It serves as a form of energy storage, primarily in the liver and muscles. This complex carbohydrate is made up of glucose units linked together, allowing animals to store energy effectively.
Step 2
B. an energy-storing lipid molecule.

Answer
This statement is incorrect. Glycogen is not a lipid molecule; it is a carbohydrate. Lipid molecules, such as fats and oils, are distinct from carbohydrates in structure and function.
Step 3
C. a molecule in which plants store sugars.

Answer
This option is also incorrect. In plants, the polysaccharide used for energy storage is starch, not glycogen. While both are carbohydrates, they serve specific roles in different organisms.

Answer
This statement is not true regarding glycogen. The polysaccharide commonly found in plant cell walls is cellulose. Glycogen, as mentioned, is associated with energy storage in animals.
