The chemical breakdown of glycogen results in the formation of glucose.

Here's why:

* Glycogen is a complex carbohydrate that serves as the storage form of glucose in animals, primarily in the liver and muscles.

* When the body needs energy, glycogen is broken down through a process called glycogenolysis.

* This process involves the removal of glucose molecules from the glycogen chain, one by one.

* The end product of glycogenolysis is glucose, which can then be used by cells for energy production.
