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).
