I got these questions wrong... (** indicates the answer i chose but it was wrong.)
1. Pancreatic juice does all of the following EXCEPT
a) buffer gastric juice
b)provide protein-digesting enzymes in inactive form.
**c) provide starch-digesting enzymes.
d) provide glucagon
e) stop the action of pepsin
2. Blood pH may be slightly elevated during digestion of a large meal because there is
a) active transport of H+ ions into the blood from the stomach
**b) active transport of H+ ions into the stomach from the blood
c) chloride ion diffusion into the stomach from the blood
d)K+ ion diffusion into the stomach from the blood.
e) loss of bicarbonate ions from the parietal cells into the blood.

Number 2 is A
I think you had the right idea here, that being that a surplus of H+ ions will make a mixture acidic. The misunderstanding was in the end part. The H+ must enter the Blood to make the Blood acidic.
Food is digested in the stomach and so naturally this is where it must diffuse from.
Question 1 I'll admit I'm not sure on.
But we can eliminate answers, obviously C isn't correct, D isn't either, as the pancreas does provide glucagon. When the pancreas dosn't do this is results in diebetes.
Pepsin is a stomach enzyme, and I have a feeling that the pancreatic juice that is introduced in the small intestine has to stop this from metabolising enzymes. So i would go for this one.
