Explain your results for Test tube P1. How did the pH influence the enzyme activity and its production of bubbles?

Part 2: Effect of temperature on Enzyme Activity  Background Information:  Each enzyme has an optimum temperature at which it works best. A higher temperature generally results in an increase in enzyme activity. As the temperature increases, molecular motion increases resulting in more molecular collisions. If, however, the temperature rises above a certain point, the heat will denature the enzyme, causing it to lose its three-dimensional functional shape by denaturing its hydrogen bonds. Cold temperature, on the other hand, slows down enzyme activity by decreasing molecular motion. In this experiment, you will explore this effect on the catalase extracted from a potato.
