Question

Quizplus · Accepted Answer

Carbon monoxide is a toxic gas that can be produced by incomplete combustion of carbon-based fuels. It binds to heme molecules in the bloodstream more readily than oxygen, resulting in a reduced ability of the body to deliver oxygen to tissues. This can lead to symptoms such as shortness of breath, dizziness, and loss of consciousness, and can even be fatal if exposure is prolonged. The fact that the man was found trapped in a running car suggests that he may have been exposed to high levels of carbon monoxide, leading to his blue coloration and difficulty breathing. Therefore, a blood test would likely reveal an abundance of carbon monoxide bound to his heme molecules.
