Carbon monoxide binds tightly to the heme groups of hemoglobin and myoglobin. How does this affinity reflect the toxicity of carbon monoxide? A. Since carbon monoxide binds the heme groups of hemoglobin, it is easily removed or replaced by oxygen. As a result, the effects of oxygen enhancement result in what divers call the "bends." B. Because carbon monoxide binds the heme groups of hemoglobin, it is easily removed or replaced by oxygen. As a result, the effects of oxygen deprivation result in suffocation. C. Because carbon monoxide binds tightly to the heme groups of hemoglobin, it is not easily removed or replaced by oxygen. As a result, the effects of oxygen deprivation result in suffocation. D. None of the above
