Question : Oxygen dissociation curve of haemoglobinis is

Answer»

sigmoid
hyperbolic
linear
hypobolic

Solution :Oxygen haemoglobin dissociation curve gives the relationship between the saturaition of haemoglobin and oxygen tension.
The curve obtained by plotting the PER CENT saturation of Hb against time is sigmoid, at 38°C and pH 7.4. Dissociation of oxyhaemoglobin can be promoted by rise in the BODY temperature and low pH (HIGH `CO_(2)`).
