  • Bioenergetics
    • Respiration
      • Aerobic
        • Exothermic
        • Glucose + oxygen --> CO2 and H2O
          • C6H12O6 + o2 --> 6CO2 + 6H2O
        • Takes longer
        • Takes more energy
        • eg. Long distance
        • Requires Oxygen
      • Anaerobic
        • Endothermic
        • Not enough/no O2
        • Glucose --> lactic acid + ATP
        • eg. a Sprint
      • Mitochondria
        • produces energy through aerobic respiration
      • Oxygen Debt
        • This is the amount of oxygen required to remove the lactic acid, and replace the body's reserves of oxygen
        • When someone who has been exercising pays back an oxygen debt, it can take from a few hours for normal exercise, to several days after a marathon.
    • Photosynthesis
      • CO2 + H2O   --> glucose + O2
      • Limiting factors limit the rate of this process
