BiologyBiological molecules, organic chemistry and biochemistryASAQA Created by: benCreated on: 30-05-13 15:31 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. 8 of 8
