In alcoholic fermentation the NADH molecules donate their electrons to other molecules derived from pyruvate, and thus an alcohol is produced. � �� ���U+�h�G{lfhb5�O㋣�&6u��2�L���L���:���؅�ԋ^����^�ŷ�ަ7&_��S������Ԓ�Д: Fermentation is a chemical breakdown of a substance by bacteria, yeasts or other microorganisms. Humans "use" alcohol fermentation in another way, co-opting it to make bread, beer, and wine. Similar to how photosynthesis requires light, cellular respiration is heavily dependent on oxygen. Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic conditions. It is generally considered an anaerobic process. 5 0 obj After glycolysis, this pathway requires two steps, which are shown in Figure 7-6. Compare and contrast lactic acid fermentation and alcoholic fermentation. %PDF-1.5 Two important functions of cells are making food and using it for energy. Lactic acid fermentation; when yeasts and bacteria convert starches or sugars into lactic acid in foods like sauerkraut, kimchi, pickles, yoghurt and sourdough bread. The alcohol byproduct that is created during fermentation is used in drinks such as beer and wine. For example, fermentation is used for preservation in a process that produces lactic acid found in such sour foods as pickled cucumbers, kombucha, kimchi, and yogurt, as well as for producing alcoholic beverages such as wine and beer.
