Tailored to the AQA specification, covering all spec points:
- The haemoglobins are a group of chemically similar molecules found in many different organisms
- Haemoglobin is a protein with a quaternary structure
- The role of haemoglobin and red blood cells in the transport of oxygen
- The loading, transport and unloading of oxygen in relation to the oxyhaemoglobin dissociation curve
- The cooperative nature of oxygen binding to show that the change
in shape of haemoglobin caused by binding of the first
oxygens makes the binding of further oxygens easier
- The effects of carbon dioxide concentration on the dissociation of
oxyhaemoglobin (the Bohr effect)
- Many animals are adapted to their environment by possessing different types of haemoglobin with different oxygen transport properties
