DESCRIPTION

Cellular respiration

Text of Cellular respiration

  • 1.ATP Production Aerobic Respiration

2. ATP

  • Adenosine Triphosphate
  • Structure
    • Base, sugar,
    • 3 phosphates
  • Phosphate bonds
    • Between two phosphates
    • Contains energy
    • Energy released when bond broken
    • Energy stored when bond created
  • ATP is recyclable

3. 4. Using ATP

  • Cells use to build molecules and organelles
  • Active transport
  • Movement (muscles)
  • Heat
  • Bioluminescence

5. Respiration

  • Purpose to produce ATP energy
  • Formula
  • C 6H 12O 6+ 6O 2 --> 6H 2O + 6CO 2+ATP energy
  • Types
    • Aerobic
    • Anaerobic (Fermentation)
  • Cellular Respiration Vs.Systemic respiration

6. Stages of Aerobic Respiration 7. Glycolysis

  • Occurs in Cytoplasm
  • Energy
    • Uses 2 ATP to get started
    • Produces 4 ATP (net gain?)
  • Reactant
    • glucose
  • Products
    • 2 pyruvic acids (pyruvate)
    • 2 NADH
      • Electron carrier
      • Carries to ETC
    • 2 ATP (net gain)

8. Glycolysis Glucose To the electron transport chain 2 Pyruvic acid http://instruct1.cit.cornell.edu/courses/biomi290/ASM/glycolysis.dcr 9. Krebs Cycle (Citric Acid Cycle)

  • Occurs in matrix of mitochondria
  • Energy
    • Produces 2 ATP
  • Reactant
    • pyruvate
  • Products
    • 8 NADH
    • CO 2
      • What happens to this?

10. Oxidative Phosphorylation (Electron Transport Chain)

  • Occurs on inner membrane of the mitochondria
  • Reactant
    • NADH
    • Oxygen
  • Product
    • H 2 O
    • 32 ATP

11. Net Gain of Aerobic Respiration

  • 36 ATP
  • CO 2and H 2 O are waste products

12. ATP Production Anaerobic Respiration: Fermentation 13. Anaerobic Respiration

  • Glycolysis + Fermentation
  • Purpose
    • Recycle NAD +
  • No more ATP
  • made

14. Types of Fermentation

  • Lactic Acid Fermentation
    • Converts pyruvate into lactic acid
    • Used by humans
    • Used to make yogurt,
    • cheese, chocolate,
    • etc..

15. Types of Fermentation

  • Alcoholic Fermentation
    • Converts pyruvate into ethanol and CO 2
    • Causes dough to rise
