Which term refers to a carbohydrate composed of many monosaccharide units joined together?

• A. Polysaccharide
• B. Disaccharide
• C. Monosaccharide
• D. Nucleotide

Answer: (A)

Many-monomer carbohydrates are called polysaccharides. They are built by linking numerous monosaccharide units through glycosidic bonds, forming long polymer chains. This makes them fit the description of a carbohydrate composed of many monosaccharide units. Examples include starch and glycogen for energy storage and cellulose for plant cell walls. In contrast, a disaccharide contains only two monosaccharide units, a monosaccharide is a single sugar unit, and a nucleotide is not a carbohydrate—it’s part of nucleic acids and includes a sugar, phosphate, and a nitrogenous base. So the best answer is polysaccharide.
