I can't figure out
Exercise 8, Activity 1=Assessing Starch Digestion by Salivary Amylase, (All of the questions Please)
1.)What do tubes 2,6, and 7 reveal about PH and amylase activity? Hint: What variable was changed in the procedure?
2.) Which PH buffer allowed the highest amylase activity? ___
3.) Which tube indicates that the amylase was not contaminated with maltose? _______
4.) Which tubes indicate that the deionized water did not contain contaminating starch or maltose? ______
5.) If we left out control tubes 3, 4, or 5, what objections could be raised to the statement: "Amylase digests starch to maltose?" (Hint think about the purity of the chemical solutions)
6.) Would the amylase present in saliva be active in the stomach? Explain your answer
7.) What effect does boiling have on enzyme activity?
