Question

complete the sentences using the words provided.

1. this diagram illustrates a (click to select) reaction.
2. glucose is a (click to select) .
3. sucrose is a (click to select) .
4. the molecule in this diagram that is commonly used as a transport sugar in plants is (click to select) .
5. the molecule in this diagram that is commonly used as a transport sugar in humans is (click to select) .
6. the glucose molecule in this diagram is shown in the (click to select) form.
7. fructose has (click to select) carbon atoms.

Explanation:

1. The diagram shows two monosaccharides combining with the loss of a water molecule, which is a condensation (dehydration synthesis) reaction.
2. Glucose is a single sugar unit, so it is a monosaccharide.
3. Sucrose is made of two monosaccharide units (glucose + fructose), so it is a disaccharide.
4. Sucrose is the main transport sugar in plants.
5. Glucose is the primary transport and energy sugar in humans.
6. The diagram shows glucose in its ring (cyclic) form, specifically α-glucose.
7. Fructose is a hexose sugar, meaning it has 6 carbon atoms.

Answer:

1. condensation (dehydration synthesis)
2. monosaccharide
3. disaccharide
4. sucrose
5. glucose
6. ring (cyclic)
7. 6
