Jaysukh Kerai 10V - SC1 Science Investigation Report - 02/02/03 Title of investigation: Factors affecting the rate of respiration in immobilised yeast. Input Variable to be investigated: The input variable that I will be investigating is the temperature. Variables to be controlled: The fixed volume, concentration of the glucose solution will have to be sustained throughout the entire investigation in order to maintain a fair test. The number and the size of the beads will also have to be kept the same, although it (size) may vary slightly, it should not have a major impact on the results. Prediction: I predict that the rate of respiration in immobilised yeast will increase with the temperature, until a particular temperature has been reached. I anticipate that as the temperature doubles, the rate of respiration will also double; that is to say that the temperature is precisely proportional to the rate of respiration. The yeast balls will respire and in effect...
