Jessica Ashton AS Practical - To investigate the course of an enzyme controlled reaction Aim To investigate how the concentration of an enzyme affects the rate of an enzyme controlled reaction, using different concentrations of diastase to see how the rate of reaction is affected. Variables that need to be controlled Variable Why this could affect the experiment How it will be controlled Temperature If the temperature fluctuates, this could easily affect the results because if the temperature gets higher or lower then the enzyme will not work as well as expected at that specific temperature and the test will no longer be fair. This will be controlled by heating both the starch and the diastase solutions in a water bath that is kept at a continual temperature of 35°c. Pressure If the pressure changes this may affect the starch and diastase and how they react together. This is hard to control but the experiment will be carried out at the normal...
