What structural difference accounts for the functional differences between starch and cellulose? A) Starch can be digested by animal enzymes, whereas cellulose cannot. B) Starch and cellulose differ in the glycosidic linkages between their glucose monomers. C) Starch is a polymer of glucose, whereas cellulose is a polymer of fructose.

Option (B).

Explanation:

Carbohydrates is one of the most important biomolecule that plays an important role in the living organism. Carbohydrates are made of monosaccharides sugars linked through glycosidic linkage.

Starch is made of the glucose residues in which the linear glucose residues are linked through alpha glycosidic linkages. Cellulose is the polymers of glucose linked through the beta glycosidic linkage. Hence, they are differ in the glycosidic linkage.

Thus, the correct answer is option (B).
