Which of the following is not correct about carbon monoxide?
A
It is produced due to incomplete combustion.
B
It reduces oxygen carrying ability of blood.
C
The carboxyhaemoglobin (haemoglobin bound to $$CO$$) is less stable than oxyhaemoglobin
D
It forms carboxyhaemoglobin
Correct option is B. The carboxyhaemoglobin (haemoglobin bound to $$CO$$) is less stable than oxyhaemoglobin
Carboxyhaemoglobin (symbol COHb or HbCO) is a stable complex of carbon monoxide and haemoglobin (Hb) that forms in red blood cells upon contact with carbon monoxide (CO). The CO-hemoglobin complex is far more stable than $$O_2$$-hemoglobin (oxyhemoglobin)
Hence statement B is incorrect.
Option B is correct.
