Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the polysaccharide used by animals to store glucose?
A
glycogen
B
fructose
C
starch
D
cellulose
Explanation: 

Detailed explanation-1: -Glycogen is a homopolysaccharide found in the liver and muscles of animals, where it is used to store energy. Chemically, glycogen is related to starch and closely resembles amylopectin.

Detailed explanation-2: -Glycogen is the storage form of glucose (energy) in animals.

Detailed explanation-3: -Glycogen is an even more highly branched polysaccharide of glucose monomers that serves a function of energy storage in animals. Glycogen is made and stored primarily in the cells of the liver and muscles. Glycogen is a branched polymer of glucose and serves as energy storage in animals.

Detailed explanation-4: -When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-5: -Glycogen is a polysaccharide that consists entirely of glucose molecules that are linked by two types of bonds-the alpha-1, 4-glycosidic bond and the alpha-1, 6-glycosidic bond. The alpha-1, 4-glycosidic bond is the more common bond and it gives glycogen a helical structure that is suitable for energy storage.
