Presentation Transcript

  1. Cellular Respiration and Fermentation

  2. Why Do Organisms Need To Respire • ATP energy! • Needed to: • Build proteins • Copy DNA • Muscle contractions • Nerve impulses • Synthesizing hormones

  3. Overview of Aerobic Respiration

  4. Aerobic Cellular Respiration • Aerobic= “with air” This process yields 36 ATP molecules!

  5. The Link BETWEEN Photosynthesis and Cellular Respiration

  6. Glycolysis • Glycolysis occurs in cytoplasm • Glyco= sweet • Lysis= to break • Results in 4 ATP per molecule of glucose

  7. Kreb’s Cycle and Electron Transport Chain • The Kreb’s Cycle and Electron transport chain occur in the mitochondrion • Produces 32 ATP molecules

  8. Overview of Aerobic Respiration

  9. Fermentation Also known as anaerobic respiration= “without air”

  10. Lactic Acid Fermentation • Bacteria in yogurt produce lactic acid • Animals experience muscle fatigue when lactic acid builds up

  11. Saccharomyces cerevisiae

  12. Alcoholic Fermentation • This process yields 4 ATP for every glucose molecule

  13. Saccharomyces cerevisiae

  14. Fermentation Also known as anaerobic respiration= “without air”
