The correct answer is A. 1000 times.
Carbon monoxide has a much greater affinity for hemoglobin than oxygen. This means that carbon monoxide is more likely to bind to hemoglobin than oxygen, and it is also more difficult to remove carbon monoxide from hemoglobin once it has bound. This can lead to a condition called carbon monoxide poisoning, which can be fatal.
Oxygen and carbon monoxide both bind to hemoglobin at the same site, but carbon monoxide has a much higher affinity for the site. This means that carbon monoxide will displace oxygen from hemoglobin, even when there is plenty of oxygen available. Once carbon monoxide has bound to hemoglobin, it is very difficult to remove. This is because carbon monoxide forms a much stronger bond with hemoglobin than oxygen does.
Carbon monoxide poisoning can occur when someone is exposed to high levels of carbon monoxide. This can happen in a number of ways, such as from a car exhaust leak, from a fire, or from using a gas stove or heater in a poorly ventilated area. Symptoms of carbon monoxide poisoning include headache, dizziness, nausea, vomiting, and confusion. If left untreated, carbon monoxide poisoning can lead to coma and death.
If you think you or someone you know may have been exposed to carbon monoxide, it is important to seek medical attention immediately. There is no antidote for carbon monoxide poisoning, but treatment can help to prevent serious complications.
