The carbon dioxide is transported via blood to lungs mostly

A

dissolved in blood plasma

B

in the form of carbonic acid only

C

in combination with haemoglobin only

D

carbaminohaemoglobin and as carbonic acid

Text Solution

Verified by Experts

The correct Answer is:
D
Most of the `CO_(2)`(70%)` that dissolves in plasma reacts ith water forming carbonic acid. This reaction occurs rapidly inside RBCs because of the presence of an enzyme carbonic anhydrease. Morevoer above 23% of total blood `CO_(2)` is transproted by loosely binding with haemoglobin forming an unstable compund called carbominahaemoglobin.
