Energy is Stored in Liver and Muscles in the form of
Glycogen is mainly stored in the liver and the muscles and provides the body with a readily available source of energy if blood glucose levels decrease. In human, the most glycogen is found in the liver (10% of the liver mass), whereas muscles only contain a relatively low amount of glycogen (1% of the muscle mass.
Muscle and liver cells have a high capacity for glycogen storage because they require fast access when the need for it arises. Glycogen stored in the muscle tissue serves an important role as well. Our muscles main function is to move bones. This allow us to do all the locomotive tasks associated with daily living.
The glucose stored in the liver serves as a buffer for blood glucose levels. Blood glucose levels are tightly regulated because glucose is the primary energy source for the central nervous system.
Muscle glycogen reserves are stored energy for the muscles. The glycogen is able to be broken back down into glucose when the muscle contracts and require energy.
