NEET BIOLOGY

Detailed explanation-1: -Starch and glycogen, examples of polysaccharides, are the storage forms of glucose in plants and animals, respectively. The long polysaccharide chains may be branched or unbranched.

Detailed explanation-2: -Storage polysaccharides Starch is the stored form of sugars in plants and is made up of a mixture of two polysaccharides, amylose and amylopectin (both polymers of glucose).

Detailed explanation-3: -Starch is a mixture of two polymers: amylose and amylopectin. Natural starches consist of about 10%–30% amylose and 70%–90% amylopectin. Amylose is a linear polysaccharide composed entirely of D-glucose units joined by the -1, 4-glycosidic linkages we saw in maltose (part (a) of Figure 14.7. 1).

Detailed explanation-4: -Cellulose is the polymer of , D-glucose and glycogen of , D-glucose. The cellulose is the polysaccharide which is present in the cell wall of the plant cells. Glycogen is the polysaccharide which is the storage form of glucose in the animal cells.

Detailed explanation-5: -Starch and cellulose are both polysaccharides of glucose.
