Other Enzymes

There are many other enzymes common to food and nutrition. Choose one you have heard of and do a little research. Propose an experiment with one of these, complete with all three types of variables named. Critique each other's experiments and suggest improvements. If you're really brave, run the experiment and report on the results. (Suggestions – Bromelain, meat tenderizer, Lactaid, lipase, Beano, etc.)
