And if we are exposed to even a small amount of carbon monoxide that comes from these processes, it can ultimately lead to the condition of carbon monoxide poisoning. Now, how exactly would one treat carbon monoxide poisoning? Well, recall that carbon monoxide and oxygen bind to the same exact location on hemoglobin, and they bind reversibly. And what that means is carbon monoxide is actually a competitive inhibitor of oxygen. So recall that in competitive inhibition, by increasing the concentration of the substrate, in this case the oxygen, we can actually cause the oxygen to outcompete the carbon monoxide for that position on the heme group of heat hemoglobin. And so, by increasing the amount of oxygen inside our blood, we can actually treat the carbon monoxide poisoning.
