8-1 question 4: judging from what you learned in this activity. suggest a reason why salivary amylase would be much less active in the stomach.

8-3 question 1 Describe the significance of the optimum pH for pepsin observed in the simulation and the secretion of pepsin by the chief cells of the gastric glands.

8-4 question 1 describe how lipase activity is measured in the simulation.  

thank you in advance for the much needed help

The pH of the stomach would alter the activity of the salivary amylase.

8-3 question 1 Describe the significance of the optimum pH for pepsin observed in the simulation and the secretion of pepsin by the chief cells of the gastric glands.

The optimum pH matches the pH secreted by gastric glands. Gastric juice is also about pH 2.
