what is the structure of haemoglobin?
quaternary
1 of 8
what are the different haemoglobins?
high affinity and low affinity haemoglobins
2 of 8
what is the difference of high and low affinity haemoglobin?
high affinity- takes up oxygen easier but releases slower. low affinity- takes up oxygen lowly but releases easier.
3 of 8
where would someone have a high affinity haemoglobin?
in mountainous areas where there isnt a lot of oxygen.
4 of 8
why does oxygen load to haemoglobin slowly at first?
because the 4 polypeptides are closely united.
5 of 8
why when 1 oxygen molecule loads to haemoglobin it is then quicker to load the rest?
because the shape changes slightly
6 of 8
what are the effects of carbon dioxide concentration?
as the carbon dioxide increases, the affinity for oxygen decreases.
7 of 8
at which part of the body has haemoglobin got a higher affinity?
in the lungs because there is little carbon dioxide.
