Bohr's Effect on Oxygen Dissociation Curve
  • The effect of carbon dioxide and pH on the oxygen dissociation curve is called the Bohr’s effect.
  • CO_{_{2}} is a major by-product of cellular metabolism. 
  • It is a nonpolar molecule and so it does not dissolve in the blood.
  • To increase its solubility, carbonic anhydrase converts the CO_{_{2}} into carbonic acid in the presence of water. 
  • Carbonic acid is a weak acid and it dissociates into bicarbonate and hydrogen ions that are soluble in blood.
  • As the concentration of hydrogen ions increases in the blood, the pH becomes acidic, affecting the oxygen binding with haemoglobin. 
  • Hydrogen ions bind to the haemoglobin at an allosteric site and the curve shifts to the right.
