The best explanation for the change in catalase activity as the pH changed from 7 to 3 is that
1 strong acid digests the catalase, causing the reaction rate to increase
2 the student most likely cooled the H2O2 solution, causing the reaction to increase
3 in acidic solutions, the shape of the catalase changes, causing the reaction rate to decrease
4 decreased oxygen production caused catalase to increase the rate of the reaction
