- Which of the following is TRUE of carbon monoxide poisoning? Group of answer choices choose one answer Carbon monoxide is toxic because it binds more readily to hemoglobin than oxygen, thereby decreasing the oxygen carrying capacity of blood. As the carbon dioxide content of blood increases, a phenomenon known as the Haldane effect converts the excess carbon dioxide to carbon monoxide until it reaches toxic levels. Carbon monoxide is toxic because it readily picks up oxygen to produce carbon dioxide, causing acidosis and eventual death. Carbon monoxide causes the carbamino effect where carbon dioxide is stripped of an oxygen, producing carbon monoxide.arrow_forwardb) Carbon monoxide (CO), also known as the "silent killer", is a colorless, odorless, tasteless gas produced by burning gasoline, wood, propane, charcoal or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels. If the early signs of CO poisoning are ignored, a person may lose consciousness and be unable to escape the danger. Co is also a respiratory inhibitor that blocks complex IV of the electron transport chain and does NOT allow for any electrons to be transferred to oxygen. Using your understanding of the electron transport chain, explain why carbon monoxide has this type of effect and how the effect leads to the overall importance of this knowledge?arrow_forwardA patient, rescued from a burning home, comes into the ER with suspected carbon monoxide poisoning.
