The "it" is glucose. If not needed by cells, it’s converted to glycogen (animal starch), the main storage form of glucose. Glycogen is formed in the liver through glycogenesis. Glycogen is in all cells, but primarily stored in the liver & skeletal muscle cells. Once the liver’s store is used up, cells break down lipids & proteins to make glucose. It’s estimated that the liver has a 4 hour store of glucose for the body.
