Data:

Enzyme rate of Catalase

Data Analysis: After conducting our experiment we discovered that the acids that we tested denatured. When denaturation occurs, denatured enzymes stops working. Denaturing an enzyme breaks the bonds that hold it together. The enzyme is incapable of putting the pieces back together for a number of reasons. It is possible they were formed during synthesis, and can't go back together after the whole enzyme is completed. Our bases traveled the whole distance just like our neutral solution.
Discussion & Conclusion:

In this lab we learned that when catalase is mixed with an acid it denatures. The unexpected result was that I thought our base would denature also but instead it did not. My data doesn’t fully support my hypothesis because our base didn’t denature only our acids did. The next time we perform this experiment we should use more peroxide to see if our paper actually denature, and we should of tested our pH level of the solution several times to get an more accurate pH level. Our weakness in this experiment was that
