Question

Why is Carbon monoxide poisonous gas ?​

Answer 1

Explanation:

Every poison has a particular trait that causes it to be poisonous. In the case of carbon monoxide, the trait has to do with hemoglobin in the blood.

Hemoglobin is made up of complex proteins that bind to iron atoms. The structure of the protein and its iron atom causes oxygen to bind to the iron atom very loosely. When blood passes through the lungs, the iron atoms in the hemoglobin bind to oxygen atoms. When the blood flows into areas of the body that are lacking in oxygen, the iron atoms release their oxygen. The difference in oxygen pressure in the lungs and in the parts of the body needing oxygen is very slight. The hemoglobin is very finely tuned to absorb and release oxygen at just the right times.

Answer 2

$\bold{\underline{\pink{\mathbb{\:carbon\:monoxide\:is\: poisonous\:gas...}}}}$

Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning — causing you to lose consciousness and suffocate... CO poisoning can be reversed if caught in time...
