Glycogen
Glycogen is a branched polysaccharide used as a readily available storage of glucose largely found in liver and muscle cells. The glycogen store in muscle is released for muscle cells, whereas the glycogen released by liver cells is released for other cells. Glycogen is broken and used when cells require more ATP than they can produce from the bloodstream [1].
