A) Inactivates nerves
B) Inhibits glycolysis
C) Combines with \[{{O}_{2}}\]
D) Combines with haemoglobin
Correct Answer: D
Solution :
[d] Carbon monoxide is colourless, odourless, and tasteless, but highly toxic. It combines with haemoglobin to produce carboxyhaemoglobin, which usurps the space in haemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's haemoglobin to convert to carboxyhaemoglobin. A level of 50% carboxyhaemoglobin may result in seizure, coma, and fatality.
