Haemoglobin

Role of Haemoglobin

to transport oxygen

needs to readily associate with oxygen at the surface where gas exchange occurs

readily dissociate oxygen at those tissues requiring it

Haemogobin changes shape to take up and release oxygen in the presence of certain substances. E.G CO2 causes haem. to change shape and relase oxygen into respiring cells.

Different Heamoglobins

Different haemoglobins have different affinities for oxygen because of their slightly different shapes. They can be made of a different amino acid sequence meaning that the shape will differ, this means that their affinty for oxygen will also change.

Oxygen Dissociation Curves(O.D.Cs)

O.D.Cs show the relationship between the partial pressure of oxygen and the saturation of haemoglobin with oxygen. Different curves show different heamoglobins and their affinity to oxygen
