Document Summary
Living organisms are all similar in that they can take energy from their. Abstract environments as a means to do biological work. Cellular respiration and alcohol fermentation are examples of this characteristic. Yeast, a single celled organism conducts fermentation when sugar is present, to make chemical energy, and in the process produce alcohol and carbon dioxide. Experiments were performed to understand this process better. One experiment focused on yeast and glucose, while another observed how yeast fermented and produced co2 with different types of sugars. Respirometers were used to record the amount of co2 production. Both experiments proved to be informative, with all expected sugars fermenting the yeast and producing carbon dioxide. However, the exact predictions made were not fully supported by the results and when comparing to the results of a different group, questions are brought to the surface on the performance the experiments. Cellular respiration is a process that most living organisms undergo to create.
