    Without doing the experiment (Did you do it?) I can't exactly tell you. Every enzyme has a pH optimum where it is most effective. Generally at either higher or lower pHs, the activity is reduced.

    If you did this experiment, the answer should be pretty obvious to you.

    pH affects everything because if the pH is 1-14 it can either slow up the reactant rate or speed it up. Depending on the level of the catalase pH and when it works the best.

    Enzymes are sensitvie to pH. Some enzymes are active

    at low pH while others are active at high pH. Just as enzymes are specific with regards to the substrate that they work on,so are they sensitive either to an Alkaline or an Acidic medium
