  • Respiration
    A process that supplies the energy needed for biological processes
  • Respiration is an exothermic reaction because it releases energy and it takes place continually in all living cells
  • Types of respiration
    • Aerobic respiration
    • Anaerobic respiration
  • Aerobic respiration
    1. Glucose reacted with oxygen gas
    2. Produces carbon dioxide and water
    3. Releases energy
  • Aerobic respiration

    Glucose molecule has been fully oxidized
  • Glucose
    Oxygen
  • Carbon dioxide
    Water
  • Anaerobic respiration in muscles
    1. Glucose converted to lactic acid
    2. Does not require oxygen
  • Anaerobic respiration releases much less energy than aerobic respiration
  • Anaerobic respiration in plants and yeast
    1. Glucose converted to ethanol and carbon dioxide
    2. Does not require oxygen
  • Fermentation
    Anaerobic respiration in yeast cells used to make alcoholic drinks and bread
