Presentation Transcript

  1. KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen.

  2. Fermentation allows Glycolysisto continue making ATP when oxygen is unavailable. • Anaerobic process • Glycolysis will happen the same way it does at the beginning of cellular respiration • Glycolysis splits glucose into two pyruvic acid molecules • Pyruvic acid and NADH enter Fermentation

  3. Fermentation will occur instead of cellular respiration due to the lack of oxygen • Occurs in the cytoplasm of cells • Fermentation does not produce ATP

  4. Two Types of Fermentation • Lactic Acid • Alcoholic

  5. Lactic acid fermentation • occurs in animal muscles when the tissue requires energy at a faster rate than oxygen can be supplied • used to convert lactose into lactic acid in yogurt and cheese production • also gives the sour taste to fermented vegetables such as pickles

  6. Alcoholic fermentation • Yeast and certain bacteria • Pyruvate is broken into alcohol and carbon dioxide • Used in the production of beer, wine and bread

  7. Uses of fermentation in industry • Sewage treatment • Biofuels • Hydrogen gas
