Question

Can you explain the answer of this question below:The maximum affinity of haemoglobin is with &ndash;A:Carbon monoxideB:CarbondioxideC:OxygenD:AmmoniaThe answer is A.

Answer

Hemoglobin in humans has a very high affinity for carbon monoxide, forming carboxyhemoglobin which is a very bright red in color. Carbon monoxide is thus problematic for humans because it has affinity higher than that of oxygen.

Answer

For hemoglobin in humans, carbon dioxide has a lower affinity than oxygen, which allows gas exchange to occur in our lungs. Carbon monoxide is problematic for us because it has an even higher affinity to hemoglobin than oxygen does.

So, option A is correct.
Thanks 4 asking...if u like then plz upvote.

Answer

CO

Answer

Haemoglobin has a tendency to combine with CO and form carboxyhaemoglobin which is too much stable than oxyhaemoglobin.

Answer

Hhemoglobin is present in blood

Answer

Understanding Hemoglobin's Affinity
Hemoglobin is a crucial protein in red blood cells that is responsible for transporting oxygen throughout the body. It has varying affinities for different gases, which affects its ability to bind and release these gases.
Maximum Affinity: Carbon Monoxide
- Hemoglobin exhibits its highest affinity for carbon monoxide (CO) compared to other gases.
- This strong attraction occurs because CO binds to hemoglobin at the same site as oxygen, but it does so much more effectively.
- When carbon monoxide binds to hemoglobin, it forms carboxyhemoglobin, which prevents oxygen from attaching and leads to reduced oxygen transport in the body.
Comparison with Other Gases
- Oxygen (O2): While hemoglobin's primary function is to carry oxygen, its affinity for oxygen is lower than that for carbon monoxide. Oxygen binds to hemoglobin, but carbon monoxide's binding is more stable and difficult to displace.
- Carbon Dioxide (CO2): Hemoglobin does bind to carbon dioxide, but its affinity is significantly lower than that for carbon monoxide. CO2 is primarily transported in the form of bicarbonate in the blood.
- Ammonia (NH3): Hemoglobin does not have a significant role in ammonia transport. The affinity of hemoglobin for ammonia is negligible compared to that for the gases mentioned above.
Conclusion
- The dangerous aspect of carbon monoxide lies in its ability to bind to hemoglobin with much greater affinity than oxygen, leading to hypoxia or oxygen deprivation in tissues. Understanding this property is crucial for recognizing the risks associated with carbon monoxide exposure.
