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.
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.
What type of reaction is carbon monoxide?
This is an example of a combination reaction.
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.
Is asphyxiation by carbon monoxide a physical or chemical process?
Asphyxiation by carbon monoxide is a physical process. Carbon monoxide competes with oxygen to bind to hemoglobin in red blood cells, preventing oxygen from being transported to tissues. This leads to oxygen deprivation, ultimately causing asphyxiation.
What two gases bind to hemoglobin?
Oxygen and carbon monoxide

Does CO2 bind at the same site on the hemoglobin molecule as O2 If not where does CO2 bind?
No. Carbon monoxide binds to the same site as oxygen, i.e. the central iron. Carbon dioxide binds to the globin molecule.
What does the hemoglobin attach to?
Hemoglobin primarily attaches to oxygen molecules in the lungs, where it binds to oxygen to form oxyhemoglobin. It can also bind to carbon dioxide, transporting it from the tissues back to the lungs for exhalation. Additionally, hemoglobin can bind to hydrogen ions and carbon monoxide, although the latter can be harmful and interfere with oxygen transport.
Which indecules does hemoglobin readity combine?
Hemoglobin readily combines with oxygen (O₂) in the lungs, where oxygen concentration is high, allowing it to transport oxygen to tissues throughout the body. It can also bind to carbon dioxide (CO₂) and hydrogen ions (H⁺), facilitating the transport of carbon dioxide back to the lungs for exhalation. Additionally, hemoglobin can interact with carbon monoxide (CO), which can bind more tightly than oxygen, posing a risk of carbon monoxide poisoning.
Does carbon monoxide compete with oxygen for the same binding site?
Yes. Carbon monoxide combines with haemoglobin to form carboxyhaemoglobin. This prevents the normal combination of oxygen with haemoglobin, thus depriving cells all round the body of the oxygen they need.
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.
What is Hemoglobin's affinity to ethane butane and propane?
I'd expect this to be negligible. The molecules which do bind to haemoglobin are oxygen, carbon monoxide and nitric oxide.
How does carbon monoxide mix with the air?
Carbon monoxide mixes with air through diffusion, which is the movement of gases from areas of high concentration to areas of low concentration. In the presence of oxygen, carbon monoxide can bind to hemoglobin in the blood, reducing its capacity to carry oxygen to cells in the body.
