<prompt> A severely depressed 32-year-old man commits suicide by running his car motor in his closed garage for several hours. The mechanism of death in this case of carbon monoxide CO poisoning is through which of the following mechanisms?Displacement of oxygen on hemoglobin by COHepatocellular necrosisInhibition of protein synthesisInhibition of the respiratory chain enzymes  <response>: CO combines with hemoglobin with an affinity 240 times greater than that of oxygen to form carboxyhemoglobin. At concentrations above 50 carboxyhemoglobin, cerebral anoxia, coma, convulsions, and death ensue. The other choices do not reflect the strong binding affinity of CO for hemoglobin.Diagnosis: Carbon monoxide poisoning
