In conclusion, the data from the experiment supports my hypothesis that catalase will function the most efficiently at a neutral pH of 7. As the pH of the solutions decreased, so did the amount of hydrogen peroxide consumed. Furthermore, after calculating the reaction rates, it is shown that the reaction rate in the solution with a pH of 7 (.5 mm/sec) was higher than any other solution. By looking at the graph above, you can see that as the pH of the solution rose to a pH of 7, catalase became more efficient and was able to better carry out its function. These results help support the idea that as a solution becomes more acidic than the optimum pH of an enzyme, the enzymes present in the solution will denature, and in turn will not be
