Biology coursework Aim To investigate how temperature affects the rate of the reaction with catalyse and hydrogen peroxide Prediction I predict that at the lower and higher temperatures the reaction will slow to the point that the reaction does not occur. This is because the enzyme will de-nature and will not break down the hydrogen peroxide. I believe that the faster reactions will be at around 20°C because this is about the temperature that the potato will be experiencing in the soil and so its natural conditions will be in effect. Plan Apparatus * 2x 5ml³ syringes * Potato puree * Hydrogen peroxide 10V * 100cm3³ measuring cylinder * bee-hive shelf * bowl * ice cream tub * kettle * ice * conical flask * tube * water Method 1. Set up apparatus as shown below 2. put catalyse extract into a syringe and put in water at set temperature for about 5 minutes for catalyse extract to heat up/cool down to correct temperature 3. put 10cm3³...
