How does temperature effect respiration? Natalie Onions Joseph Whitaker School To investigate how temperature effects respiration, we would have to use something which contains living enzymes so that the limitations of which temperatures can be investigated are present. If enzymes are exposed to temperatures too far above or below their optimum range, they will denature and the experiment will be unsuccessful. (Nelson's Modular Science book). Equipment: Yeast solution (20gramms for each temperature) Beaker Water Scales Kettle Clamp stand Conical flask Gas syringe Sugar Spatula Measuring cylinder Thermometer Stopwatch Bubble wrap The Gas syringe was the most useful piece of equipment made available to us. A pipe is connected to a bung and placed on top of the conical flask. The other end was then connected to the gas syringe. The yeast will be respiring aerobically and so will be producing Carbon Dioxide gas. If the yeast should, for any reason, start to respire anaerobically, it will still produce carbon dioxide gas. This is the gas that we...
