Major quantity of carbon dioxide is transported in human body in the form of
Options
(a) carbo haemoglobin
(b) carbonic acid
(c) sodium and pottasium bicarbonates
(d) calcium bicarbonate
Correct Answer:
sodium and pottasium bicarbonates
Explanation:
About 7% of carbon dioxide transported is dissolved in plasma. About 23% loosely binds with haemoglobin as carbaminohaemoglobin and about 70% reacts with water forming carbonic acid in erythrocytes in the presence of enzyme carbonic anhydrase. Carbonic acid is soon converted into H⁺and HCO₃̄(bicarbonate) ions. This HCO₃̄ion comes out of RBCs and combines with Na⁺and K⁺to form bicarbonates of these ions.
