What molecule is produced when glycogen is hydrolyzed?

When glycogen is hydrolyzed, the primary product is glucose-1-phosphate. Glycogen, which serves as the stored form of glucose in the body, undergoes a process called glycogenolysis during which it is broken down into glucose units to meet energy demands. The hydrolysis reaction involves the enzymatic cleavage of the glycogen chain, resulting in the release of glucose-1-phosphate molecules.

Glucose-1-phosphate can subsequently be converted into glucose-6-phosphate, which is a key intermediate in various metabolic pathways, including glycolysis and gluconeogenesis. This process is crucial, particularly during periods of increased energy expenditure, as it provides readily accessible glucose for use in aerobic or anaerobic respiration.

The other molecules listed do not directly arise from glycogen hydrolysis. Fructose, for example, is a simple sugar derived from sources like fruits but is not a product of glycogen breakdown. Similarly, galactose is another simple sugar found in dairy products and is not related to glycogen hydrolysis. Lactate is produced during anaerobic metabolism of glucose but is not a direct product of glycogen breakdown. Thus, glucose-1-phosphate is the correct and relevant molecule produced from the hydrolysis of
