Solution:
The oxygen–haemoglobin dissociation curve is sigmoid, which represents the relationship between oxygen concentration and percentage saturation of haemoglobin. The rise in temperature or fall in pH shifts the curve to the right, whereas at decreased temperature and rise in pH, the curve becomes more steep. Low temperature increases the affinity of haemoglobin towards oxygen.
