प्रश्न

Explain why, it is dangerous to inhale air containing carbon monoxide.

टिप्पणी लिखिए

उत्तर

Carbon monoxide combines with haemoglobin and forms carboxyhaemoglobin by replacing the oxygen. This reduces the oxygen carrying capacity of the blood. Due to the lack of oxygen, the person cannot breathe properly. In extreme cases, a person may even die due to oxygen starvation. Hence, it is dangerous to inhale the air containing carbon monoxide.
