The structure & function of haemoglobin

  • recall that the haemoglobins are a group of chemically similar molecules found in many different organisms.
  • recall that is a protein haemoglobin is a protein¬†with a quaternary structure
  • describe the role of haemoglobin in carrying oxygen and carbon dioxide with reference to the role of carbonic anhydrase, the formation of haemoglobinic acid and carbaminohaemoglobin (details of the chloride shift are not required)
  • describe and explain the significance of the oxygen dissociation curves of adult oxyhaemoglobin at different carbon dioxide concentrations (the Bohr effect)
