Define oxygen dissociation curve class 11

WebThe sigmoidal pattern of oxygen haemoglobin dissociation curve is the result of two properties which play significant role in the transport of oxygen. These two properties are: (i) Minimal loss of oxygen from haemoglobin occurs above p02 of 70-80 mm Hg despite significant changes in tension of oxygen beyond this. WebOxygen dissociation curve is the sigmoid curve obtained when the percentage saturation of haemoglobin with O 2 is plotted against the partial pressure of oxygen p O 2. It helps in the study of the effect of factors like pC O 2, H + concentration etc. on binding of oxygen with haemoglobin. The binding of oxygen to haemoglobin is in such a way that the …
