1. In the body, the lactase enzyme functions to break down lactose during digestion. In light of this, what approximate pH would you expect lactase to be most active? Did your results in table 4 agree or disagree with your expectations for optimal pH?

2. In the presence of naturally occurring enzymes in fruits and vegetables was discussed. Using your results from this exercise as a basis to guide your thoughts, do you think that cooked, frozen, or raw fruits and vegetables would contain the most active enzymes?
