    Cellular respiration Cellular respiration Presentation Transcript

    • Cellular Respiration What we do with our energy
    •  
    • Anaerobic vs. aerobic
      • Uses no oxygen
      • Makes a little energy
      • Uses oxygen
      • Makes a lot of energy
    • Overview Of Cellular Respiration
      • Cellular respiration is the process that releases energy by breaking down glucose and other molecules in the presence of oxygen.
        • Occurs in the Mitochondria
      • To release energy from food molecules and make ATP!
      • Why do we need ATP?
        • ATP is the energy molecule needed by our cells
        • Our cells use ATP to make all of the chemical reactions in our body run.
      Purpose of cellular respiration?
    • Summary equation for Respiration
    • What if there is no Oxygen?
    • Anaerobic respiration
      • Not enough oxygen for aerobic respiration
      • Fermentation-releases energy from food molecules by producing ATP in the absence of oxygen. (Anaerobic = no oxygen)
      • Two types: alcoholic fermentation, lactic acid fermentation
    • Lactic acid vs alcoholic
      • No oxygen
      • Occurs in muscles
      • Pyruvates  lactate
      • Occurs so muscles can continue making ATP
      • Get lactate build up in muscles
      • Causes soreness
      • No oxygen
      • Pyruvate  carbon dioxide & ethanol
      • Seen in yeast and fungus
      • Used to make beverages, food, makes dough rise
    • Overall
      • Cellular Respiration breaks down Glucose (C 6 H 12 O 6) .
      • It produces H 2 O and CO 2
      • It produces 36 ATPs!
    • Comparing Photosynthesis & Cellular Respiration Photosynthesis Cellular Respiration Function Energy capture Energy Release Location Chloroplasts Mitochondria Reactants Carbon dioxide and water Glucose and oxygen Products Glucose and oxygen Carbon dioxide and water
