Question

part 3: real-world application
scenario: you are studying why some people cannot digest milk properly (lactose intolerance).
lactose intolerance

1. which enzyme is responsible for breaking down lactose?
2. what happens when someones body doesnt produce enough of this enzyme?

breacking down conplex chemicals is much slower

1. how might understanding enzymes help doctors treat this condition?

part 4: reflection

Explanation:

1. Identified the enzyme from the normal digestion diagram.
2. Summarized the outcome shown in the lactose intolerant pathway.
3. Connected enzyme function to targeted treatment for the condition.

Answer:

1. Lactase
2. Lactose is not broken down, leading to undigested lactose in the large intestine which causes symptoms like gas, bloating, cramping, and diarrhea.
3. Doctors can recommend lactase enzyme supplements to help break down lactose, or advise dietary changes to avoid or limit lactose-rich foods, based on the knowledge that the lack of lactase causes the condition.
