A) Chloroform
B) Carbon dioxide
C) Carbon monoxide
D) Carbon disulphide
Correct Answer: C
Solution :
Carboxyhaemoglobin, a stable compound, is formed when haemoglobin readily combines with carbon monoxide. Carbon monoxide converts (II) to iron (III) in its reaction with haemoglobin. In this form haemoglobin does not carry oxygen resulting in its (oxygen) starvation and leads to asphyxiation and in extreme cases to death. The affinity of haemo- globin for CO is 250 times its affinity for\[{{O}_{2}}\]and COHb liberates CO very slowly and also due to that compound the dissociation curve of the remaining\[Hb{{O}_{2}}\] shifts to the left, decreasing the amount of \[{{O}_{2}}\]released.You need to login to perform this action.
