Use pipette to add 2% fructose to tube 1. 0000002987 00000 n much of that sugar) is present. Another error in this lab would have been the temperature of the water since the waters temperature was not consistently measured, and since the water could have been colder in one of the experiment then the other this could have affected the fermentation because enzymes work better in hotter temperatures and if one is colder than the other this would mean the fermentation could have been less efficient. Water, To determine the rate of fermentation, I will measure the hight of the CO2 bubble produced. has entered the pipette at time = 20 minutes and subtracting the amount of water that }. Includes kit list and safety instructions. The energy of glucose is used as fuel by nearly all living organisms to stay alive, to maintain homeostasis, and run all kinds of life activities. Carefully swirl the Erlenmeyer flask and record the initial readings. There is a difference between cellular respiration and fermentation. 0000002829 00000 n (McGraw-Hill). Start timer.

Web. System status in real time, .bs3-nav-link-support a{ In fermentation, the Conclusion: Plants and Animals, .bs3-nav-link { The lack of yeast in Tube 1 and the lack of a significant amount of glucose in Tube 2 represented the control groups as well as the need for both reactants to be present in a solution in order for fermentation to occur and produce CO2. Therefore with greater mass of sucrose in the fermentation of yeast, the greater the production of CO2 in the reaction, resulting in lower pH levels.
