How does the concentration of hydrogen peroxide affect how the enzymes in potatoes work? In this experiment I will see the affects of reacting different concentrations of hydrogen peroxide with the enzymes in potatoes. Potatoes contain the enzyme catalyse and this enzyme reacts with the hydrogen peroxide to form oxygen and water. The reaction can be seen by the formula: 2H²O² 2H²O + O² (hydrogen peroxide) (water + oxygen) I will obtain sets of results by varying the concentration of hydrogen peroxide used; this will affect the rate of reaction and, in turn, oxygen given off within a certain time period will vary accordingly. I will change the concentration of hydrogen peroxide by diluting it with distilled water. It is vital that certain factors are kept constant throughout the investigation in order to carry out a 'fair test'. The factors that must remain un-altered are: * Temperature. This has to be kept the same because enzymes work best...
