Does anyone have any secondary data for an experiment testing pepsin and temp?

For my  Science Investigation twe had to test how temperature affected enzyme activity.
We tested 5 different temperatures 0, 20,40,60 and 80 degrees with 1ml of pepsin in each test tube and put in the corresponding water bath. After 5 minutes we took them out and added 3 drops of acid and 2ml of albumen. We then timed how long each test tube took to turn clear using a stopwatch. Has anyone got link to a similar practical experiment with results? I can credit you in my reference page if you have any secondary data that can be useful.
thanks i need it for tomorrow and searched all over the internet put haven't found anything related to this experiment.
