Detailed explanation-1: -Glucose is the main source of fuel for our cells. When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-2: -Glycogen stores in skeletal muscle serve as a form of energy storage for the muscle itself; however, the breakdown of muscle glycogen impedes muscle glucose uptake from the blood, thereby increasing the amount of blood glucose available for use in other tissues.

Detailed explanation-3: -Glycogen is a ubiquitous fuel source stored in the cytosol of cells, occupying 2% of the volume of cardiac cells, 10 1%–2% of the volume of skeletal muscle cells, and 5%–6% of the volume of liver cells.

Detailed explanation-4: -Glycogen is the storage form of carbohydrates in mammals. In humans the majority of glycogen is stored in skeletal muscles (∼500 g) and the liver (∼100 g).

Detailed explanation-5: -The muscles and organs need a certain level of glucose in the blood to work properly. When the body is missing an enzyme or has a flawed enzyme and is not able to use glycogen the right way, it leads to a condition called glycogen storage disease (GSD).
