Cellular respiration

  1. 1. ATP Production Aerobic Respiration
  2. 2. ATP <ul><li>Adenosine Triphosphate </li></ul><ul><li>Structure </li></ul><ul><ul><li>Base, sugar, </li></ul></ul><ul><ul><li>3 phosphates </li></ul></ul><ul><li>Phosphate bonds </li></ul><ul><ul><li>Between two phosphates </li></ul></ul><ul><ul><li>Contains energy </li></ul></ul><ul><ul><li>Energy released when bond broken </li></ul></ul><ul><ul><li>Energy stored when bond created </li></ul></ul><ul><li>ATP is recyclable </li></ul>
  3. 4. Using ATP <ul><li>Cells use to build molecules and organelles </li></ul><ul><li>Active transport </li></ul><ul><li>Movement (muscles) </li></ul><ul><li>Heat </li></ul><ul><li>Bioluminescence </li></ul>
  4. 5. Respiration <ul><li>Purpose – to produce ATP energy </li></ul><ul><li>Formula </li></ul><ul><li>C 6 H 12 O 6 + 6O 2 --> 6H 2 O + 6CO 2 + ATP energy </li></ul><ul><li>Types </li></ul><ul><ul><li>Aerobic </li></ul></ul><ul><ul><li>Anaerobic (Fermentation) </li></ul></ul><ul><li>Cellular Respiration Vs. Systemic respiration </li></ul>
  5. 6. Stages of Aerobic Respiration
  6. 7. Glycolysis <ul><li>Occurs in Cytoplasm </li></ul><ul><li>Energy </li></ul><ul><ul><li>Uses 2 ATP to get started </li></ul></ul><ul><ul><li>Produces 4 ATP (net gain?) </li></ul></ul><ul><li>Reactant </li></ul><ul><ul><li>glucose </li></ul></ul><ul><li>Products </li></ul><ul><ul><li>2 pyruvic acids (pyruvate) </li></ul></ul><ul><ul><li>2 NADH </li></ul></ul><ul><ul><ul><li>Electron carrier </li></ul></ul></ul><ul><ul><ul><li>Carries to ETC </li></ul></ul></ul><ul><ul><li>2 ATP (net gain) </li></ul></ul>
  7. 8. Glycolysis Glucose To the electron transport chain 2 Pyruvic acid http://instruct1.cit.cornell.edu/courses/biomi290/ASM/glycolysis.dcr
  8. 9. Kreb’s Cycle (Citric Acid Cycle) <ul><li>Occurs in matrix of mitochondria </li></ul><ul><li>Energy </li></ul><ul><ul><li>Produces 2 ATP </li></ul></ul><ul><li>Reactant </li></ul><ul><ul><li>pyruvate </li></ul></ul><ul><li>Products </li></ul><ul><ul><li>8 NADH </li></ul></ul><ul><ul><li>CO 2 </li></ul></ul><ul><ul><ul><li>What happens to this? </li></ul></ul></ul>
  9. 10. Oxidative Phosphorylation (Electron Transport Chain) <ul><li>Occurs on inner membrane of the mitochondria </li></ul><ul><li>Reactant </li></ul><ul><ul><li>NADH </li></ul></ul><ul><ul><li>Oxygen </li></ul></ul><ul><li>Product </li></ul><ul><ul><li>H 2 O </li></ul></ul><ul><ul><li>32 ATP </li></ul></ul>
  10. 11. Net Gain of Aerobic Respiration <ul><li>36 ATP </li></ul><ul><li>CO 2 and H 2 O are waste products </li></ul>
  11. 12. ATP Production Anaerobic Respiration: Fermentation
  12. 13. Anaerobic Respiration <ul><li>Glycolysis + Fermentation </li></ul><ul><li>Purpose </li></ul><ul><ul><li>Recycle NAD + </li></ul></ul><ul><li>No more ATP </li></ul><ul><li>made </li></ul>
  13. 14. Types of Fermentation <ul><li>Lactic Acid Fermentation </li></ul><ul><ul><li>Converts pyruvate into lactic acid </li></ul></ul><ul><ul><li>Used by humans </li></ul></ul><ul><ul><li>Used to make yogurt, </li></ul></ul><ul><ul><li>cheese, chocolate, </li></ul></ul><ul><ul><li>etc.. </li></ul></ul>
  14. 15. Types of Fermentation <ul><li>Alcoholic Fermentation </li></ul><ul><ul><li>Converts pyruvate into ethanol and CO 2 </li></ul></ul><ul><ul><li>Causes dough to rise </li></ul></ul>
  15. 16. Cellular Respiration Flow Map C 6 H 12 O 6 + 6O 2 - -> 6H 2 O + 6CO 2 + ATP energy Glucose + 2 ATP Oxygen
