Experiment 6A11. You may need to let students know that at pH values above 10, enzymes will becomedenatured and the rate of activity will drop. If you have pH buffers higher than 10, havestudents perform an experimental run using them.SAMPLE RESULTSSample class dataTest tube labelSlope, or rate (%/min)5 Drops xxxx10 Drops xxxx20 Drops xxxx0 – 5 °C range: 4°C xxxx20 – 25 °C range: 21 °C xxxx30 – 35 °C range: 34°C xxxx50 – 55 °C range: 51°C xxxxpH 4pH 7pH 10xxxxxxxxxxxxThe effect of H 2 O 2 concentration on the rate ofenzyme activityThe effect of pH on the rateof enzyme activity6A - 2 TBiology with Vernier
