Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is a large molecule of many simple sugars?
A
Monosaccharide
B
Disaccharide
C
Polysaccharide
D
Googlesaccharide
Explanation: 

Detailed explanation-1: -Cellulose is a polysaccharide consisting of a linear chain of several hundred to many thousands of linked glucose units.

Detailed explanation-2: -Polysaccharides may be made from thousands of simple sugars linked together. These large molecules may be used for storage of energy or for structure.

Detailed explanation-3: -A polysaccharide is a large molecule made of many smaller monosaccharides. Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers, or polysaccharides. A polysaccharide is also called a glycan.

Detailed explanation-4: -As the name implies, polysaccharides are large high-molecular weight molecules constructed by joining monosaccharide units together by glycosidic bonds. They are sometimes called glycans. The most important compounds in this class, cellulose, starch and glycogen are all polymers of glucose.

Detailed explanation-5: -The disaccharides are composed of two monosaccharides linked together, and polysaccharides are composed of 3 or more monosaccharides linked together.
