WHICH OF THE FOLLOWING DIGESTIVE FUNCTIONS CAN OCCUR IN THE MOUTH?

A. Enzymatic action on protein
B. Absorption of water
C. Enzymatic action on carbohydrates
D. Secretion of bile

Since this is not my area of expertise, I searched Google under the key words "saliva enzyme" to get these possible sources:

http://en.wikipedia.org/wiki/Saliva

http://www.woodrow.org/teachers/chemistry/institutes/1988/starch.html

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
