G.C.S.E Biology Experiment to Show the Respiration Rate in Yeast Introduction This experiment has been set up to show the respiration rate in yeast over a range of different temperatures. I have done this to find at what temperature yeast respires the highest. I will be using a range of temperatures from 10?C to 70?C with intervals of 10?C. After using the temperatures 20?C and 40?C in my pilot experiment, I will repeat the experiment with a range of temperatures being: 10?C, 20?C, 30?C, 40?C, 50?C, 60?C and 70?C. I will be using this wider range to find the optimum heat capacity. Hypothesis I predict that the yeast's respiratory rate of reaction should increase in speed as the temperature increases. However this may at some point peak and therefore cease to increase in speed as I predict at some point the enzymes causing the yeast to respire will become denatured. The point of this investigation...
