Question

Since hemoglobin is attracted more to carbon monoxide than it is to oxygen, what is likely to happen to a person if he breathes in excessive amounts of carbon monoxide? He would exhale deadly carbon gas. He could go blind. He could suffocate from lack of oxygen in his blood. He could have a massive heart attack.

Answer 1

C. He could suffocate from lack of oxygen in his blood.

Given the statement that hemoglobin (used to transport oxygen throughout our body) is more attracted to carbon monoxide, it is highly likely that most, if not all, the hemoglobin in a human body will be bound to carbon monoxide instead of oxygen when a person inhales too much carbon monoxide. This results in a lack of hemoglobin carrying oxygen to the cells of the body. Oxygen deficiency occurs.
