What compounds make up cellulose?
A
amino acids
B
enzymes
C
sugars
D
lipids
Explanation: 

Detailed explanation-1: -Unlike amylose, cellulose is made of glucose monomers in their form, and this gives it very different properties.

Detailed explanation-2: -Cellulose is a linear polymer glucan and is composed of glucose units (> 10 000), which are linked by -(1–4)-glycosidic bonds.

Detailed explanation-3: -Cellulose is a linear polymer of glucose molecules in which individual glucose units are connected via acetal linkages between the C1 and C4 carbons of the glucopyranose rings (Figure 1) (24).

Detailed explanation-4: -Cellulose is a polysaccharide which consists of several repeating units of monosaccharide D-Glucose. Thus, it cannot be broken down into simpler compounds. Hence, cellulose is not a simple sugar. Hence, option (b) is the only correct answer, cellulose is a carbohydrate.
