Pre-Lab Exercise 233 Digestive Enzymes Brush border enzymes

Solution

Table 23.1 can be updated as below:

Enzmye	Source	Function
Salivary amylase	Salivary glands	Breakdown of starch to sugar.
Pepsin	Gastric cells	Convert proteins to peptides. They are capable of doing so in a highly acidic pH.
Trypsin	Intestinal cells	Convert proteins to peptides. They are capable of doing so in a slightly basic pH.
Pancreatic lipase	Pancreas	Hydrolysis of fats to fatty acids and glycerol.
Brush border enzymes	Brush border cells of small intestine	Aminopeptidases convert peptides to amino acids. Maltase converts maltose to glucose. Sucrose converts sucrose to glucose and fructose. Lactose converts lactose to glucose and galactose.
