Digestive System: Enzymatic Digestion and Absorption Worksheet

Digestive System: Enzymatic Digestion and Absorption

1. List the three major nutrient classes (a.k.a. macronutrients).

1. CARBOHYDRATES

2. LIPIDS

3. PROTEINS

2. Which of the following carbohydrates is not a disaccharide?

a. maltose
b. lactose
c. starch - IS NOT A DISACCHARIDE
d. sucrose

3. Match the following pairs of molecules with their monomers by placing the number next to the matching
letter:

a. sucrose - GLUCOSE + FRUCTOSE

b. maltose - GLUCOSE + GLUCOSE

c. starch - MANY GLUCOSE MONOMERS

d. lactose - GLUCOSE + GALACTOSE

The monomers:

1. many glucose monomers
2. glucose + fructose
3. glucose + galactose
4. glucose + glucose

4. The breakdown products (monomers) of proteins are AMINO ACIDS.

5. The breakdown products of triglycerides include monoglycerides and FATTY ACIDS.
