Students did an experiment comparing the activity of four different enzymes, A, B, C, and D. The results are represented in the graph below. The Effect of pH on Enzyme Activity B 1. Acid 7. Base 14 pH A valid conclusion based on the information in the graph is that the pH of some enzymes changes as the temperature changes a difference in the pH of an environment changes enzyme activity enzymes change color in proportion to the rate of activity enzyme activity causes acids to change into bases over time Relative Rate of Enzyme Activity
