The gas which combine with haemoglobin to damage its oxygen carrying capacity is

A

`CO_(2)`

B

`O_(2)(g)`

C

`CO(g)`

D

`N_(2)(g)`

Text Solution

Verified by Experts

The correct Answer is:
C
Carbon monoxide is the only gas among the given choices that destroys the oxygen carrying capacity of heamoglobin. CO is physiologically quite inert and has no unique toxic action on body tissues but its affinity for haemoglobin is about 300 times that of `O_(2)`. The reaction between CO and Hb is, however, reversible.
`HbO_(2) +CO Leftrightarrow HbCO+O_(2)`
