Introduction: fermentation a metabolic process with occurs in the absence of oxygen molecules also known as an anabolic reaction it is a process of glycolysis in which sugar molecules are used to create atp. In this process, known as yeast fermentation, there are 2 atp molecules produced for each glucose molecule fermented the products from one glucose molecule are two molecules of ethanol and two molecules of carbon dioxide (jorgensen, 1911). Yeast fermentation the purpose of this experiment was to observe the process in which cells must partake in a respiration process called anaerobic fermentation and as the name suggests, oxygen is not required.
