Which molecule is a polysaccharide?
A
Triglyceride
B
Lactase
C
Glycerol
D
Glycogen
Explanation: 

Detailed explanation-1: -Glycogen is a glucose polysaccharide occurring in most mammalian and nonmammalian cells, in microorganisms, and even in some plants. It is an important and quickly mobilized source of stored glucose.

Detailed explanation-2: -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.

Detailed explanation-3: -Starch, cellulose, and glycogen are some examples of polysaccharides.

Detailed explanation-4: -Common examples of polysaccharides are cellulose, starch, glycogen, and chitin. Cellulose is a polysaccharide consisting of a linear chain of (1
