10.2: Chemical Digestion and Absorption
Which nutrients are broken down by these enzymes? Write the chemical equation
for each.
In the Mouth (pH of 7)
Salivary Amylase:
In the Stomach (pH of 2)
Pepsin:
In the Small Intestine (pH of 8)
Pancreatic amylase:
Sucrase:
Maltase:
Lactase:
Pancreatic Lipase:
Trypsin:
Chymotripsin:
Peptidases:
Absorption: How are the following absorbed? How are they transported?
Monosaccharides:
Amino Acids:
Glycerol & Fatty Acids:
Learning Check:
1. Where do most of the enzyme reactions related to digestion occur? [k/u]
2. Why is it necessary to break down macromolecules before they are absorbed in the
small the small intestine? [k/u]
3. What might be the consequences if a person has their pancreas removed? Why?
