  • Respiration
    • respiration and burning of fossil fuels are similar chemical processes...
      • both release energy from fuel
        • they're exothermic
      • both produce waste products
      • both require oxygen
      • both require fuel
    • the amount of energy released depends on the conditions where the chemical reaction takes place...
      • coal burns easier if there is plenty of oxygen
    • if no oxygen is present...
      • anaerobic respiration
        • 2 ATP
        • found in the cytoplasm
        • glucose ? lactic acid (+energy)
          • energy available for use in cells
    • if oxygen is present...
      • aerobic respiration
        • 38 ATP
        • found in the mitochondria
        • glucose + oxygen ? carbon dioxide + water (+energy)
          • energy available for use in cells
