Yeast is a good example of an organism that undergoes alcoholic fermentation. The same process that goes on in the mitochondria during lactic acid fermentation also happens in alcoholic fermentation. The only difference is that the byproduct of alcoholic fermentation is ethyl alcohol.
Yeast uses fermentation the same way we use cellular respiration-for energy. Yeast cells will take glucose and convert it into ATP in the absence of oxygen, yielding many by â¦ products, but the one of interest for us is ethyl alcohol, or ethanol.east and a few other microorganisms use alcoholic fermentation, forming ethyl alcohol and carbon dioxide as waste.
