Part 3
5. What was the optimal temperature for amylase? Explain how your iodine test
results support your answer.
5
6. Why did the enzyme activity differ in the ice bath compared to the boiling water
bath?
Part 4
7. What was the optimal pH for amylase? Explain how your iodine test results
support your answer.
8. Pepsin is an enzyme that hydrolyzes proteins in the stomach.
a. The pH in the stomach is 2. What do you think the optimum pH of
pepsin would be?
b. What happens to the activity of pepsin when it enters the small intestine
where the pH is 8?
