Answer:
Glycogen.
Step-by-step explanation:
Glycogen may be defined as the energy stored molecules of the animal cells. Glycogen is made of the glucose molecules that are linked together through the glycosidic linkages.
The excess energy containing nutrients is converted into the form of glycogen in the cells. Excess glucose is stored in the form of glycogen. The glycogen molecule is formed in excess blood glucose levels and start breaking in the low blood glucose level.
Thus, the answer is glucose.
