Which category does glucose belong to?

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

Answer: (A)

Glucose is a monosaccharide, the simplest form of carbohydrate consisting of a single sugar unit. Monosaccharides are the basic building blocks of carbohydrates, and they cannot be broken down into smaller carbohydrate units. When two sugar units join, they form disaccharides; when many units link together, they form polysaccharides like starch or glycogen. Oligosaccharides are short chains of a few sugar units, more than one but not many. Since glucose is a single sugar unit, it belongs to the monosaccharide category.
