The monomeric unit of cellulose is
Correct answer: A. Glucose
- A. Glucose
- B. Fructose
- C. Mannose
- D. Ribose
Explanation
Cellulose is a polysaccharide that consists of long chains of glucose molecules. Specifically, it is made up of β-D-glucose units linked by β-1,4-glycosidic bonds. This structure provides the rigidity and strength of plant cell walls. The other options, fructose, mannose, and ribose, are monosaccharides that do not form cellulose. Fructose is found in sucrose, mannose is involved in other polysaccharide structures, and ribose is a component of RNA, not cellulose.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
