Include notation as to where the (1) amount of enzyme used is regulated (2) amount of substrate provided is shown and (3) amount of product measured is located. Also take class notes on the biochemistry of catalase, including proposed mechanism of the reaction, the variety of toxins metabolized by catalase, and two inhibitors of catalase reaction, one competitive, one, non-competitive.
Enzymes are sensitive. Each enzyme acts at a specific temperature, specific pH, and on a specific substrate (food upon which the enzymes act). For example, salivary amylase (found in the saliva of the mouth) works best at neutral pH, whereas gastric enzymes work best in acidic medium, and the intestinal or pancreatic enzymes work best in basic medium.
