Got Lactase?

This lesson will allow students to observe and identify evidence of an enzyme's activity, lactase, and its function, and action on a substrate found in milk, lactose. They will then relate the absence of lactase to the condition of lactose intolerance, which many students or family members of students experience. Enzymes are a type of protein essential to life and necessary for many of the metabolic reactions that occur in the human body. Since these reactions occur at the molecular level within the body, students do not directly observe enzymes functioning.
