Fermentation Introduction Fermentation is an anaerobic reaction (does not require oxygen) that converts pyruvic acid produced by glycolysis into lactic acid or alcohol and carbon dioxide (1). After glycolysis, if there is no oxygen present then fermentation occurs which produces ethyl alcohol and carbon dioxide (2). Fermentation does not produce any ATP or energy, instead it allows the cell to recycle NADH into NAD+ which permits glycolysis to occur, which then produces some energy. Since alcohol is made through the fermentation of yeast. In order to learn the effect of alcohol concentration on the fermentation ability of yeast, we did an experiment regarding fermentation. If alcohol concentration ends up
