[glī′kōjenol′isis]
Etymology: Gk, glykys + genein + lysis, loosening
the breakdown of glycogen to glucose.

(glī'kō-jĕ-nol'i-sis)
The hydrolysis of glycogen to glucose.

glycogenolysis

The process of breakdown of GLYCOGEN to release molecules of GLUCOSE.

Glycogenolysis

The process of tearing-down a glycogen molecule to free up glucose.

glycogenolysis

removal of a glucose molecule from glycogen, by the action of the enzyme glycogen phosphorylase, present in liver, kidneys, muscle and brain. The products are a glycogen molecule that is one glucose residue shorter than before and glucose-1-phosphate. This in turn is converted to glucose-6-phosphate, from which free glucose can be released from the liver and kidneys (but not from skeletal muscle or brain) by the action of glucose-6-phosphatase. See also glucose, glycolysis.

glycogenolysis

hydrolysis of glycogen into glucose

gly·co·gen·ol·y·sis

(glī'kō-jĕ-nol'i-sis)
The hydrolysis of glycogen to glucose.

glycogenolysis (gli´kōjēnol´isis),

n the formation of blood glucose by hydrolysis of stored liver glycogen.

glycogenolysis

the splitting up of glycogen in the liver or muscle, yielding glucose-1-phosphate.

muscle glycogenolysis
metabolic process under the regulatory control of adrenergic hormones or calcium ions for providing a rapid supply of ATP for muscle contraction and movement, particular for type II fibers. See also glycogen phosphorylase.
