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

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.
