Step 1 of 3

Glycogenesis (Glycogen synthesis)

It is the formation of Glycogen from glucose when high levels of adenosine triphosphate in the cells begin to inhibit glycolysis.

Glycogen is synthesized from glucose-6-phosphate, principally in the liver and skeletal muscle. It is stored within these tissues as glycogen granules. The synthesis of Glycogen takes place on a glycogen primer protein called glycogenin.

Glycogenolysis (Breakdown of Glycogen)

The process of breakdown of Glycogen to glucose is called Glycogenolysis. The terminal glucose residue is removed from the non-reducing end by the enzyme glycogen phosphorylase. Glucose-6-phosphate obtained from the Glycogen is converted into glucose in the liver and kidneys. Thus, the liver glycogen helps to maintain the blood glucose levels when glucose levels begin to fall.
