Coursework: To investigate the effect of temperature changes to the activity of Enzyme Catalyses. By Marcus Final update: 26/11/03 Apparatus needed: Boiling tubes Beakers Bung with a delivery tube Thermometer 5ml syringe (To collect potato) 10ml syringe (To measure the amount of solution) Diced potato Bunsen burner (can be replaced by thermosactic water bath if possible) Ice Glass rod Hydrogen peroxide pH 7 buffer Variable and invariable factors: ØpH of enzyme: This can be done by the …

…H2O2 used may not be the same every time. If I measured 11ml of H2O2 (instead of 10ml), the rate of reaction would have been affected. This also happens to the volume of potato used. To minimize the error, I have to make sure the volume is accurate every time. I considered this experiment to be successful, despite a few minor errors had been made. The result proved that my assumption was correct.
