    Cards (7)

    • Hemoglobin is a proteins with a quaternary structure (more than one polypeptide chain)
    • the role of haemoglobin is to transport oxygen around the body by loading, transporting and unloading
    • what is haemoglobin made of ?
      • 4 polypeptide chains
      • each with a iron containing haem group
    • what is cooperative binding?

      when the first oxygen molecule binds causing it to change shape slightly allowing oxygen to bind more easily now
    • haemoglobin has an affinity for oxygen
    • Oxygen + haemoglobin = Oxyhaemoglobin
    • why is haemoglobin useful?
      • can change its affinity for oxygen under different conditions
