The Effects of Temperture on Yeast Growth and Fermentation

Introduction The purpose of this experiment is to determine the effect that temperature has on the growth and respiration of yeast fermentation. The growth and respiration of the yeast can be determined by using a glucose/ yeast solution mixed with water in flasks set at different temperatures. Yeast in order to produce, has to make energy, to carry out all cellular functions (Spicer, Holbrook, 2007). The concept that aerobic metabolism of all yeasts, is determined by the relative sizes of the transport rate of sugar into the cell and the transport rate of respiratory into the mitochondrion. (Barford, 1990) â€Å"Yeast is of various one-celled fungi that can cause the fermentation of carbohydrates, which can lead to producing carbon†¦show more content†¦Again four trials were done in ten minute intervals and the data recorded. Then the first flask was removed and placed on a warmer till the temperature reached 35 degrees Celsius or 95 degrees Fahrenheit. The flask was then put back into the set up with the tubes connecting the solution to the water flask. Again four trials were done in intervals of 10 minutes apart with the data recorded. Then the solution flask was
