Question

Complete hydrolysis of cellulose gives (a) D-ribose (b) D-glucose(c) L-glucose (d) D-fructose

Answer 1

The answer is b) D-glucose.

Cellulose is present in the cell wall of plants and contains numerous d-glucose units linked together by β-glycosidic linkages in a linear chain.

Hydrolysis is the process of breakdown of a compound by its reaction with water.

So when cellulose is completely hydrolyzed, the β-glycosidic linkages are broken down resulting in D-glucose units.
