Alcoholic Fermentation: Alcoholic fermentation occurs in yeast and other microorganisms. A microorganisms own metabolite: referred to as a product from a natural or genetically improved strain. This indicates how strong in your memory this concept is. Research on the chemistry of alcoholic fermentation in the second half of the 19th and beginning of the 20th century greatly facilitated the progress of biochemistry in general (seeFERMENTATION). Glycolysis is the chemical breakdown of glucose to lactic acid. Yeasts are responsible for this process, and oxygen is not necessary, which means that alcoholic fermentation is an anaerobic process. The fermentation of carbohydrates into Alcohol is one of the oldest known chemical processes. 1 Name: _____ Alcoholic Fermentation in Yeast All living cells, including the cells in your body and the cells in yeast, need energy for cellular processes such as pumping molecules into or out of the cell or synthesizing needed molecules. Lactic Acid Fermentation: Lactic acid fermentation occurs in Lactobacillus spps, yeast, and muscle cells. Progress % Practice Now.
