  • Respiration
    • Respiration is the process of transferring energy from glucose which goes on in every cell - continuous
    • Aerobic
      • Respiration using oxygen
      • Most efficient way to transfer energy from glucose
      • Continuous in plants and animals
      • Mainly occurs in the mitochondria
    • Anaerobic
      • Means "without oxygen'
      • Body shifts to this form of respiration during vigorous exercise when your body can't supply enough oxygen to your muscles
      • Does not transfer as much energy as aerobic respiration - glucose isn't fully oxidised (doesn't combine with oxygen)
      • Useful in emergencies - allows you to use your muscles for a little longer during exercise
      • Plants and yeast cells can respire without oxygen - but they produce ethanol and carbon dioxide instead of lactic acid
        • In yeast cells this is called fermentation
          • used to make bread and alcoholic drinks
            • Carbon dioxide makes the bead rise (bread-making) and alcohol is produced (drinks industry)
