  • Anaerobic Respiration
    • Anaerobic respiration is the absence of air. not using oxygen
    • in yeast cells: glucose - ethanol + carbon dioxide
    • in yeast cells: C6H12O6 - 2C2H50H + 2CO2
    • in muscle cells: glucose - lactic acid (+ some energy)
    • in muscle cells: C6H12O6 - 2C3H6O3 (+ some energy)
    • Using yeast
      • Wine making
      • Beer Making
      • Baking bread
    • Exercise
      • Exercise uses up available O2 and the body can't supply enough O2 to the tissues.
    • provides energy to keep the muscle going for longer but produces lactic acid.
    • the lactic acid builds up in the blood stream causing cramps
    • To get rid of the lactic acid the muscle must be oxidised. This is called repaying the oxygen debt.
