D
Glycogen are polymers of
E
Cellobiose is repeating disaccharide in cellulose
Explanation: 

Detailed explanation-1: -The repeating unit of cellulose is cellobiose, a disaccharide of glucose in which there is a 180° rotation of each monomer in relation to its neighbor.

Detailed explanation-2: -Despite nomenclature conventions of the International Union of Pure and Applied Chemistry and the International Union of Biochemistry and Molecular Biology, the repeating unit of cellulose is often said to be cellobiose instead of glucose.

Detailed explanation-3: -Cellulose is made up of repeating units of monomer glucose.

Detailed explanation-4: -Cellobiose is the structural unit of cellulose molecules and also the main product in enzymatic hydrolysis of cellulose. It has been identified that cellobiose can strongly inhibit hydrolysis reaction of cellulase, whereas it has no effect on the adsorption of cellulase on cellulose surface.

Detailed explanation-5: -Cellobiose is similar to cellulose in having glucose constituents. However, cellulose is a polysaccharide, which means that it is made up of several monosaccharide (particularly, glucose) units joined together. Cellobiose forms when cellulose is partially hydrolyzed by the enzyme cellulase.
