Firstly, glycogen is a polysaccharide of glucose (made up from lots of glucose monomers), and functions as the primary short term energy storage in animal cells (mostly in liver).
When the organism needs energy, it sends a signal (hormones: adrenaline and glucagon) to the cells of the liver, so that they would start decomposing glycogen (separating it into its smaller parts - glucose). Then glucose is secreted (thrown out) into the blood, so that other cells can use it to do work.
If you need a more scientific explanation:
When a signal molecule of adrenaline or glucagon attaches to the receptor of the glycagon containing cell, the receptor activates adenylyl cyclase (transmembrane protein), which converts ATP to cAMP (cyclic adenine monophosphate). cAMP activates protein kinase A (PKA), which activates phosphorilase kinase b, which then activates glycogen phosphorilase. Only then glycogen phosphorilase catalyses the reaction of glycogen decomposure into glucose.

What is the energy storing polysaccharides for animals?
Glycogen
The energy-storing polysaccharide of plants?
STARCH.NovaNet
What is the function of glycogen granules in bacteria?
Our bodies way of storing carbohydrates.
What organ in a mammal is responsible for storing glycogen?
Mainly the liver but Glycogen is also found in muscles too.
Energy storing polysaccharide of animals?
A. Glycogen just answered it on plato lol.
What is the main organ for storing starch?
The main organ that stores the starch is called as liver. It stores about 150 grams of glycogen. Glycogen is animal starch. The total mass of muscles also store about 150 grams of glycogen.
Why are complex carbohydrates better for storing energy than simple sugar?
Simple sugar molecules will create lot of osmotic pressure in the cell. In case of glycogen, you have thousands of glucose molecules put together. Glycogen molecule is compact and does not produce much osmotic pressure.
What are three ways in which the liver helps humans maintain homeostasis of glucose levels?
The liver helps humans maintain homeostasis of glucose levels in three ways. They include storing excess glucose as glycogen, releasing glycogen during fasting, and using precursors in gluconeogenesis.
Animal cells store excess sugar in the form of a polysaccharide called starch?
Starch is stored by plants.Animals' storing carbohydrate is glycogen.
What are the advantages of the liver storing glycogen as a form of energy instead of glucose?
glycogen is a more complex carbohydrate than glucose. macromolecules are stored as complex molecules for example lipids are stored as complex fat.
What is the smallest polysaccharide?
glycogen
What is an important molecule that is used by organisms to store this released energy?
The chief food energy storing molecule used by organisms is carbohydrates. Glycogen is a carbohydrate storage molecule which is employed by animals.
