| Abstract | In this laboratory, students investigate the effects of enzyme concentration, substrate concentration, pH and temperature on the activity of catalase. Activity is measured by soaking filter paper discs in catalse, dropping the discs into hydrogen peroxide and timing how long it takes them to rise. Rate of activity = depth of catalase/rising time. Includes data tables. |
