Final answer:
Glycogen is the molecule that stores carbohydrates for later use in animals.
Step-by-step explanation:
Glycogen is the molecule that stores carbohydrates for later use in animals. It is the animal equivalent of starch and is made up of monomers of glucose. Glycogen is a highly branched molecule usually stored in liver and muscle cells. Whenever blood glucose levels decrease, glycogen is broken down to release glucose in a process known as glycogenolysis.
