  1. Fermintation 4.6

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

  3. Microbes Anaerobic and Arobic • http://player.discoveryeducation.com/index.cfm?guidAssetId=E7965B93-1D6D-4740-8C55-D6E80EDB4C49&blnFromSearch=1&productcode=US

  5. Fermentation allows glycolysis to continue. • Fermentation allows glycolysis to continue making ATP when oxygen is unavailable. • Fermentation is an anaerobic process. • occurs when oxygen is not available for cellular respiration • does not produce ATP

  6. Fermentation allows glycolysis to continue making ATP when oxygen is unavailable. • NAD+ is recycled to glycolysis • Lactic acid fermentation occurs in muscle cells. • glycolysis splits glucose into two pyruvate molecules • pyruvate and NADH enter fermentation • energy from NADH converts pyruvate into lactic acid • NADH is changed back into NAD+

  7. Fermentation and its products are important in several ways. • Alcoholic fermentation is similar to lactic acid fermentation. • glycolysis splits glucose and the products enter fermentation • energy from NADH is used to split pyruvate into an alcohol and carbon dioxide • NADH is changed back into NAD+ • NAD+ is recycled to glycolysis

  8. yogurt • Fermentation is used in food production. • cheese • bread
