Question

which list correctly shows carbohydrates in size from smallest to largest?
○ monosaccharide, disaccharide, polysaccharide
○ disaccharide, polysaccharide, monosaccharide
○ disaccharide, monosaccharide, polysaccharide
○ polysaccharide, disaccharide, monosaccharide

Explanation:

To determine the correct order of carbohydrates from smallest to largest, we analyze the structure of each type:

• Monosaccharides are the simplest (smallest) carbohydrate units, as they are single sugar molecules (e.g., glucose, fructose).
• Disaccharides are formed by the combination of two monosaccharide units (e.g., sucrose is glucose + fructose), so they are larger than monosaccharides.
• Polysaccharides are long chains of many monosaccharide units (e.g., starch, glycogen), making them the largest among the three.

So the order from smallest to largest is monosaccharide, disaccharide, polysaccharide.

Answer:

A. monosaccharide, disaccharide, polysaccharide
