Yes - haemoglobin has a higher affinity for carbon monoxide than oxygen. This means that it will bind to carbon monoxide in preference.
The binding of carbon monoxide at one site of the haemoglobin increases the affinity for oxygen at the other 3 sites - which may cause problems as the oxygen is not released when it should be.
Yes, irreversible while with oxygen reversible
Yes, that's why you suffocate if you get stuck in a car with the exhaust coming in. The Carbon Monoxide sticks to your haemoglobin so the oxygen cannot.

Why does carbon monoxide bind to hemoglobin?
Carbon monoxide binds to hemoglobin because it has a higher affinity for hemoglobin than oxygen does. This means that carbon monoxide can displace oxygen from hemoglobin, leading to a decrease in the amount of oxygen that can be transported in the blood.
Is carboxyhemoglobin hemoglobin carrying oxygen?
No, carboxyhemoglobin is a complex of carbon monoxide with hemoglobin, which reduces the ability of hemoglobin to carry oxygen. It can be formed when carbon monoxide is inhaled, leading to carbon monoxide poisoning.
How does the effectiveness of carbon monoxide bonding to hemoglobin compare to that of oxygen?
Carbon monoxide has a higher affinity for hemoglobin than oxygen does. This means that carbon monoxide binds more strongly to hemoglobin, reducing the ability of oxygen to bind and be transported in the blood.
Does carbon monoxide bind to hemoglobin or oxygen better?
Carbon monoxide binds to hemoglobin with a higher affinity than oxygen, forming carboxyhemoglobin. This can displace oxygen from hemoglobin, reducing the blood's ability to transport oxygen to tissues, which can lead to serious health consequences.
What is the complex that forms when carbon monoxide and hemoglobin combine?
The complex that forms when carbon monoxide and hemoglobin combine is carboxyhemoglobin. This complex is formed when carbon monoxide binds to the heme group in hemoglobin with a higher affinity than oxygen, reducing the ability of hemoglobin to carry oxygen to the tissues.
How does carbon monoxide affect oxygen?
Carbon monoxide reduces the oxygen saturation of hemoglobin at any given PaO2.
Which gases will replace oxygen in blood hemoglobin?
Carbon monoxide will replace, and displace, oxygen on hemoglobin. This is why carbon monoxide poisoning is so dangerous as the tissues slowly lose access to oxygen.
Why is oxygen saturation normal in carbon monoxide poisoning?
In carbon monoxide poisoning, oxygen saturation may appear normal because carbon monoxide binds more strongly to hemoglobin than oxygen, preventing oxygen from binding effectively. This can lead to tissue hypoxia despite normal oxygen saturation levels.
What two gases bind to hemoglobin?
Oxygen and carbon monoxide
Carbon monoxide combines with what component of blood?
Carbon monoxide combines with hemoglobin in the blood to form carboxyhemoglobin, which reduces the blood's ability to carry oxygen.
The bloods ability to carry oxygen is blocked by?
Carbon monoxide binds to hemoglobin in the blood more readily than oxygen, reducing the blood's ability to carry oxygen effectively. This can lead to carbon monoxide poisoning, which can be life-threatening.
What is the definition of carboxyhemoglobin?
Carboxyhemoglobin is a compound formed by the binding of carbon monoxide to hemoglobin in the blood. This binding reduces the blood's oxygen-carrying capacity, leading to symptoms of carbon monoxide poisoning.
