Lesson 1.2 Lactase Lab

Another Trait: Lactose Intolerance People who are lactose intolerant cannot eat or drink dairy products Symptoms: Stomach cramps Bloating Diarrhea Throwing up Can take a supplement called lactase to help them digest dairy better.

So you decide you want to help people with lactose intolerance or other similar traits… What jobs could you get?

Stuff you remember from your high school biology class… Lactose is the sugar in milk. Lactase is a type of protein called an enzyme that digests it. No Lactase = Lactose Intolerance Glucose Galactose Lactose

Stuff you remember from your high school biology class… Glucose Galactose Lactose Lactase Glucose Galactose + Lactase Cells need glucose for cellular respiration. People who are lactose intolerant don’t have enough lactase to break down lactose. One option is to take Lactaid. Lactaid is the enzyme lactase that helps lactose intolerant people break down lactose.

Testing for Glucose Glucose test strips indicate presence or absence of glucose in a solution
