  2. Do Now! Chapter 4: Cells and Energy Section 6: Fermentation • While taking notes in his biology class, Joel made the chart below. • Which terms correctly complete his chart? • A. Chloroplasts ; Mitochondria • B. Reactants; Products • C. Creates; Uses • D. Aerobic; Anaerobic

  3. Chapter 4: Cells and Energy Section 6: Fermentation Agenda • Finish up previous Presentation • Fermentation (presentation) • Respiration Jeopardy or • Respiration Flowchart activity

  4. Chapter 4: Cells and Energy Section 6: Fermentation What does this…  …have in common… …with this?

  5. Chapter 4: Cells and Energy Section 6: Fermentation Fermentation!

  6. Chapter 4: Cells Section 6: Fermentation • Ferment-ation • When oxygen levels are low, cells can’t use aerobic processes, like cellular respiration. • Instead, they switch to anaerobic processes to make ATP (energy). • Glycolysis is anaerobic, but it needs to recharge after each cycle.

  7. Chapter 4: Cells Section 6: Fermentation

  8. Chapter 4: Cells Section 6: Fermentation • Ferment-ation • Fermentation is the process that allows glycolysis to continue. • After glycolysis breaks glucose into 2 pyruvates, fermentation happens. • During fermentation, pyruvate is converted to one of either two things: • Lactic acid (in animals) • Ethanol (in plants and fungi)

  9. Chapter 4: Cells and Energy Section 6: Fermentation 2 ATP! With O2 Cellular Respiration 2 ATP! Electron Carriers! (NADH) Electron Carriers (NADH) Electron Transport Chain 32-34 ATP!

  10. Chapter 4: Cells and Energy Section 6: Fermentation 2 ATP! Without O2 Lactic Acid (animals) Ethanol (plants&fungi) OR
