Respuesta :

The major source of glucose released to elevate a low blood glucose level is glycogen. If the blood glucose level falls to dangerous levels , the alpha cells of the pancreas release glucagon, a hormone whose effects on liver cells act to increase blood glucose levels. The hormone converts glycogen into glucose a process called glycogenolysis. 

Answer:

Glycogen.

Explanation:

Glycogen may be defined as the polymers of the glucose linked through the glycosidic bonds. The glycogen is the storage form of the glucose present in the animal cells.

The low blood glucose level stimulates the secretion of glucagon hormone. This hormone causes the breakdown of glycogen into the sugar molecules and glucose. Glucose then absorbed by the blood and mainatins the blood glucose level up to the normal level.

Thus, the answer is glycogen.
