  1. Cellular Respiration EQ:

  2. Our bodies use energy for… ENERGY We get this energy from breaking the bonds of Organic Molecules!

  3. 2 ways to obtain the most common fuel, c6h1206… 2. Get it elsewhere! • Heterotrophs • Animals • Fungi • Bacteria Cellular Respiration • Make your own! • Autotrophs • Plants • Algae Photosynthesis

  4. Glucose can’t directly fuel life processes… CONVERSION CONVERSION C6H12O6 is converted into ATP = usable Energy

  5. Human conversion efficiency… $100.00 $100 worth of food fuel $40 worth of ENERGY

  6. ENERGY is lost as HEAT

  7. when the body needs energy, what happens… In the first few seconds After 15/20min From 1-3s  90s From 90s  15/20min

  8. In the first few seconds… • ATP stored in your muscles is used up!

  9. From 1-3s90s… C6H12O6 • The body’s cells don’t have a large supply of O2 • ANAEROBIC RESPIRATION No O2 pyruvate C6H12O6 2 ATP LACTIC ACID pyruvate Glycolysis Lactic Acid Fermentation

  10. Anaerobic respiration Advantages • Fast Energy Boost Disadvantages • Lactic Acid buildup = muscle fatigue • Only 2 ATP from 1 glucose (10% efficient) O2 gets rid of the Lactic Acid…breathing rate will increase!

  11. From 90s to 15/20min… Once breathing rate …more O2 is available! AEROBIC RESPIRATION CO2 H2O O2 36 ATP pyruvate

  12. aerobic respiration Disadvantages • Needs O2 • Not for Quick bursts of ENERGY Advantages • Continuous supply of ENERGY • 36 ATP from 1 glucose (38% efficient)

  13. After 15/20min… • Glucose stores are depleted! • The body uses other organic molecules • Lipids • Proteins

  14. Cellular Respiration: Equation C6H12O6 + 6O2 (38)ATP + 6CO2 + 6H2O ase
