Effects of pH on Enzyme Activity

The rate of catalase activity at pH 2.0 was 44 seconds, 45 seconds, and 44 seconds.

The rate of catalase activity at pH 7.4 was 25 seconds, 23 seconds, and 19 seconds.

The rate of catalase activity at pH 10.4 was 27 seconds, 27 seconds, and 24 seconds.

Our inital hypothesis was that the more acidic the pH, the faster the reaction would be. However, our observations are not consistent with these thoughts. Based on our observations, the more basic the pH, the faster the reaction. However, the discrepancies between neutral and the more acidic pH are not necessarily supportive of this summary and require further observation.
