Experiment to show how temperature effects respiration in yeast Introduction: Yeast is a single-celled fungus which respires anaerobically (respiration not requiring oxygen). It breaks down sugar into alcohol. SUGAR --> ALCOHOL + CARBON DIOXIDE + ENERGY The factors which would affect the rate of respiration are what temperature the yeast is at and the concentration of the glucose. I have decided to investigate how the temperature affects the rate of respiration. Prediction: In this experiment the temperature will affect the way in which yeast respires. I predict that the temperature at which the rate of reaction will be fastest is at 37ºC. This is because enzymes work best at the temperature of 37ºC (this is the optimum temperature for respiration). If the temperature is above this the enzymes break down and stop working causing respiration to stop as the enzymes denature. However if the temperature is less than 37ºC it will...
