  • Respiration
    • burning
      • fossil fuels + oxygen ? carbon dioxide + water + energy
        • energy = heat and light
    • cellular
      • takes place in the cells of organisms
        • converts energy into ATP
          • releases waste products
      • releases heat
      • reactions are catabolic
        • breaks larger molecules into smaller ones
          • as weak "high energy" bonds are replaced into stronger ones
    • ATP
      • when it breaks down
        • energy created is used by the cell for processes..
          • muscle contractions
          • DNA replication
          • active transport
      • main respiratory substrate used is 6-carbon glucose
        • is oxidised from carbon dioxide
          • the energy released is used to synthesise ATP from ADP and Pi
