Cellulose, the primary component of plant cell walls, is composed of glucose molecules joined together through specific glycosidic bonds. Choose the option that accurately describes the structure of cellulose.
Cellulose consists of a straight chain of glucose molecules connected by β-1,4 glycosidic bonds, with branching occurring at specific sites through α-1,6 glycosidic bonds.
Cellulose is composed of an unbranched chain of glucose molecules linked by β-1,4 glycosidic bonds.
Cellulose comprises a branched chain of glucose molecules connected by α-1,6 glycosidic bonds at the branching sites.
Cellulose is made up of an unbranched chain of glucose molecules linked by α-1,4 glycosidic bonds.
Cellulose is a polysaccharide made up of repeating units of glucose molecules. These glucose units are connected by β-1,4 glycosidic bonds, which means that the glucose molecules are linked together in a linear, unbranched chain.While cellulose is an important constituent of plant cell walls, it does not contain branching or α-1,6 glycosidic bonds. Instead, it forms a long, straight chain through the β-1,4 glycosidic bonds.
Therefore, option 2 correctly describes the structure of cellulose as an unbranched chain of glucose molecules linked by β-1,4 glycosidic bonds.
