1.Draw equations to show how carbon dioxide affects the blood concentration of H+ (and thus the pH) and the blood concentration of HCO3-. Indicate the directions of change in these values if blood carbon dioxide levels were to rise.
2. Use the equation shown in question 1 to explain how hyperventilation and hypoventilation affect the blood pH.
3. In procedure B, which tube showed the most digestion of egg albumin? What can you conclude about the pH optimum of pepsin?
4.In procedure C, which test tube displayed the most rapid fall in pH? Explain the reason for this, including an explanation of how the digestion of fat can cause a fall in the pH of the solution, and the function of bile salt.
N0.5 question is test your analytical ability
5.Suppose, in performing procedure A, the test for starch and for reducing sugars both came out positive after a 1-hour incubation, but after the tubes incubated for 2 hours, the test for starch came out negative. How could you explain these results?
