1. 1 Fermentation “NO Oxygen” (called anaerobic). Occurs in cytoplasm when “NO Oxygen” is present (called anaerobic). glycolysis fermentation Remember: glycolysis is part of fermentation. Two Types: Two Types: 1.Alcohol Fermentation 2. Lactic Acid Fermentation

2. 2 Alcohol Fermentation Plants and Fungi  alcohol, makes dough rise Plants and Fungi  alcohol, makes dough rise glucose Glycolysis CCCCCCCCCCCCC CCCCCC 2 Pyruvic acid 2ATP 2ADP + 2 2NADH P 2 NAD + CCCC 2 Ethanol 2CO 2 released 2NADH 2 NAD +

3. 3 Alcohol Fermentation End Products: Alcohol fermentation End Products: Alcohol fermentation 2 - ATP 2 - CO 2 2 - Ethanol’s

5. 5 Lactic Acid Fermentation End Products: Lactic acid fermentation End Products: Lactic acid fermentation 2 - ATP 2 - Lactic Acids -Production of cheese, yogurt, buttermilk, and sour cream – the acid contributes to the sour taste. -Pickles and sauerkraut are produced by lactic acid.
