Question

Quizplus · Accepted Answer

Carbon monoxide is a toxic gas that can bind to hemoglobin with greater affinity than oxygen, which means it can replace oxygen in the blood pigment hemoglobin and reduce the transport of oxygen to the brain. This can lead to hypoxia, a condition in which the body tissues do not receive enough oxygen to function properly. Carbon dioxide, methane, and sulfur dioxide can also affect respiration and cause health problems, but they do not have the same ability as carbon monoxide to replace oxygen in hemoglobin.
