Answer;
-Glycogen
The organic molecule called glycogen is formed of branched chains of sugar units.
Explanation;
-Glycogen is a branched polysaccharide of glucose that serves as a form of energy storage in humans, animals, fungi, and bacteria.
-In humans, glycogen is made and stored in liver and muscle cells. Muscle cell glycogen is broken down into glucose, and liver glycogen is broken down into glucose as a circulating energy source glucose for use by the body.
-Glycogen is accumulated in response to insulin and broken down into glucose in response to glucagon. It plays a major role in maintaining the blood-glucose levels, which is vital since some organs in the body such as the brain purely depend on glucose for energy.
