Question

Carbon monoxide is a pollutant because:

• A. It reacts with $O_2$
• B. In inhibits glycolysis
• C. It reacts with haemoglobin
• D. It makes nervous system inactive

Answer 1

The correct option is C It reacts with haemoglobin

Carbon Monoxide has a high affinity towards haemoglobin than oxygen. It reacts immediately forming carboxyhaemoglobin. Since carboxyhaemoglobin (COHb) releases carbon monoxide slowly, less haemoglobin will be available to transport oxygen from the lungs to the rest of the body.
