Lab Report On Fermentation Of Yeast

Fermentation of Yeast

Abstract

Because living organisms are similar in their processes, they are all expected to uptake energy from their environments in order to perform biological work. Examples of such processes include cellular respiration and fermentation.In the experiment we performed, yeast served as an organism that in the presence of glucose,conducted fermentation to make chemical energy,in the process producing alcohol and carbon dioxide as products. The experiment that was conducted by the Biology class focused on the usage of a respirometer to measure the amount of CO2 produced by the fermentation of yeast in presence of glucose. The experiment proved to be concise and practiced a logical approach to showing how the sugars led to the yeast fermenting and producing CO2 levels in accord to the amount of yeast used.(Symbiosis,2016)

Introduction

Cellular respiration is one of the most important biological processes that encompasses life on Earth. Without it, cells would die,and there would be limited sources of life. In order for organisms to make chemical energy in the form of ATPA, cellular respiration is used. Cellular respiration has three main stages in which ATP is synthesized,those being: Glycolysis, Krebs cycle

After the experiment was performed, we were able to conclude and confirm the hypothesis that the more yeast in presence of glucose, the greater the rate of fermentation is. According to Freeman, 2016, yeast performs fermentation in the absence of oxygen. Our experiment simulated the anaerobic process of fermentation and yielded the results based on the original prediction that the glucose levels changed the amount of starting material yeast had to work with in order to produce carbon dioxide. The process of fermentation of the glucose is dependent on the yeast present
