WebLactose-Lactase Experiment Purpose: This lab will examine the specificity of an enzyme (lactase) to a specific substrate (lactose). Students will observe the actions of the enzyme and how shape is important to enzyme reactions. Introduction Lactose, the sugar found in milk, is a disaccharide composed of glucose and galactose (both six sided ... WebJan 10, 2012 · related substrate molecules. The reason for this is that the active site of the enzyme is complementary to the shape and polarity of the substrate. Typically, only one kind of substrate will “fit” into the active site. In this experiment, we will work with the enzyme amylase. This enzyme is responsible for hydrolyzing starch.
