Question

Using your knowledge of prefixes that we have learned this Unit, which of the following carbohydrates do you think has the largest molecule size?

Question 24 options:

Glucose (a monosaccaride)


Cellulose (a polysaccaride)


Lactose (a disaccaride)

Answer 1

Among the options provided, **cellulose** (a polysaccharide) has the largest molecule size.

Here's a brief explanation of each:
- **Glucose** is a monosaccharide, meaning it is a single sugar molecule.
- **Lactose** is a disaccharide, composed of two monosaccharide units (glucose and galactose).
- **Cellulose** is a polysaccharide, consisting of many (often hundreds to thousands) glucose units linked together.

Because polysaccharides are made up of long chains of monosaccharide units, they typically have much larger molecular sizes compared to monosaccharides and disaccharides.
