Review Sheet 25
14. Fill in the following chart about the various digestive system enzymes described in this exercise.
Digestive Enzymes
15. Name the end products of digestion for the following macromolecules:
proteins:
carbohydrates:
em Substrate(s)
Key:
Why did very little, if any, digestion occur in test tube 5T?
catalyst
control
enzyme
substrate
16. In the exercise concerning trypsin function, how could you tell protein hydrolysis occurred?.
Why was tube 1T necessary?.
Why was tube 2T necessary?
Why was 37°C the optimal incubation temperature?.
Why did very little, if any, digestion occur in test tube 3T?.
329
Optimal pH
Trypsin is a protein-digesting enzyme similar to pepsin, the protein-digesting enzyme in the stomach. Would trypsin
work well in the stomach?
Why or why not?
