  1. Cellular Respiration & Fermentation Chapter 8

  2. Cell Respiration • All organisms need energy from food. They obtain this energy through a process called cellular respiration.

  3. Remember ATP!!

  4. THERE ARE 2 TYPES OF RESPIRATION!

  5. Anaerobic Respiration(Fermentation) • Uses NO OXYGEN and produces little energy from glucose – only 2ATP • Starts with the process of GLYCOLYSIS in the CYTOPLASM • C6H12O6 + 2 ATP  2 pyruvic acid + 4 ATP (start up energy) (3-C Compound) (gain of 2 ATP)

  6. Pyruvic Acid Breakdown in Some Organisms • Break it down into waste products to be excreted • Bacteria/Yeast – break it down into alcohol and CO2 • Mammal Muscle Cells – turns into lactic acid • BOTH PROCESSES MAKE 2 ATP in the ABSENCE of OXYGEN

  7. PAUSE FOR A DEMONSTRATION!!

  8. Aerobic Respiration • Requires the presence of Oxygen • Takes place in the mitochondria • COMPLETELY breaks down glucose molecule to generate large amounts of energy (36 ATP)

  9. 2 Processes Involved in Aerobic Respiration • Krebs (Citric Acid) Cycle • Electron Transport Chain

  10. Steps: • First, Glycolysis occurs (in the cytoplasm) generating 2 Pyruvic Acids and 2 ATP • Next, Oxygen is used to completely breakdown the pyruvic acid and make CO2 and H2O as wastes and 34 more ATP • As you can see this is MUCH more efficient than anaerobic respiration, WHY?
