Question

The polysaccharides made up of glucose monomers are

• A. sucrose, lactose, maltose
• B. chitin, glycogen, starch
• C. starch, glycogen, cellulose
• D. starch, inulin, peptidoglycan

Answer 1

The correct option is C starch, glycogen, cellulose

Polysaccharides are the carbohydrate that has more than two units of monosaccharide linked together by glycosidic bonds. Starch is a polysaccharide of glucose in which the bonds are 1-4 glycosidic bonds. It is the energy storing compound of the plant and it has a linear chain which has Alpha 1-4 linkage and branched chain which is alpha 1-6 linkage.

Glycogen is a branched polymer of glucose and contains around 30,000 units of glucose it is also known as animal starch because it is a storage product in animals. In glycogen, glucose molecules are linked by 1-4 glycosidic linkage and straight line and 1-6 linkage branched part.

Cellulose is an important constituent of the cell wall which is made up of an unbranched chain of 6000 beta D glucose generate links by 1-4 glycosidic linkage.

So, the correct option is 'starch, glycogen, cellulose'
