Question

Cellulose is polymer of 

• A. Glucose
• B. Fructose
• C. Ribose
• D. Sucrose

Answer 1

The Correct Option is A

To determine the correct answer to the question of which sugar cellulose is a polymer of, let's explore the details:

Cellulose is an organic compound, a major component of the cell wall in plants, that provides structural support. It is a polysaccharide, meaning it is a large molecule composed of repeating structural units (monomers). In this case, the monomer units are glucose molecules.

The structure of cellulose consists of long chains of glucose units linked together by β(1→4) glycosidic bonds. This particular linkage leads to the formation of linear chains that can pack tightly, providing the rigidity and high tensile strength that is characteristic of cellulose.

1. Glucose: This is the correct answer as cellulose is comprised of glucose monomers. Each glucose unit is linked through β(1→4) bonds, which are essential for the structure of cellulose.
2. Fructose: This is not correct. Fructose is a different type of sugar molecule and does not typically form polysaccharides like cellulose.
3. Ribose: This is not correct. Ribose is a five-carbon sugar involved in the structure of RNA, not cellulose.
4. Sucrose: This is not correct. Sucrose is a disaccharide composed of glucose and fructose, not a polymer like cellulose.

Therefore, the correct answer is Glucose, as cellulose is a polymer made up of glucose units linked by β(1→4) glycosidic bonds.
