Respiration

• Respiration is exothermic because it releases energy and takes place in all living cells
• Aerobic respiration (releases a lot of energy because glucose molecule has been fully oxidated)

  glucose + oxygen -> carbon dioxide + water
• aerobic respiration -

  symbol equation

  C6H12O6 + O2 -> Co2 + H2o
• Anaerobic respiration in MUSCLES - (DOES NOT USE OXYGEN and produces much less energy because oxidation of glucose is incomplete)


  Glucose —> lactic acid
• Anaerobic respiration - PLANT CELLS AND YEAST CELLS (no oxygen)


  glucose —> ethanol + carbon dioxide
