Question

Cellulose, the most important constituent of plant cell wall is made of

(a) unbranched chain of glucose molecules linked by α  1, 4 glycosidic bond

(b) branched chain of glucose molecules linked by β 1, 4 glycosidic bond in straight chain and α 1, 6 -glycosidic bond at the site of branching

(c) unbranched chain of glucose molecules linked by β  1, 4 glycosidic bond

(d) branched chain of glucose molecules linked by α 1, 6 glycosidic bond at the site of branching

Answer 1

Correct option  (c) unbranched chain of glucose molecules linked by β  1, 4 glycosidic bond

Explanation :

Cellulose (C₆H₁₀O₅ ), is the most abundant organic polymer. It is a polysaccharide and consists of long unbranched chains of glucose residues linked by β, 1 4 glycosidic bonds. In plants, cellulose is formed from sugar. It serves as building material in the formation of cell wall.
