Arrange the affinity of hemoglobin (Hb) towards $ \mathrm{CO} $, $ \mathrm{CO_2} $, and $ \mathrm{O_2} $ in increasing order.

Question

As per ABO blood grouping system, the blood group of father is $B^+$ , mother is $A^+$ and child is $O^+$. Their respective genotype can be
A. $I^B i/I^A i/ii$
B. $I^B I^B /I^A I^A /ii$
C. $ I^A I^B /iI^A /I^B i$
D. $I^A i/I^B i/I^A i$
E. $iI^B /iI^A /I^A I^B$
Choose the most appropriate answer from the options given below :

Answer 1

Hemoglobin's (Hb) affinity for various gases is dictated by their chemical interactions with the heme group. The affinity order is as follows: Carbon monoxide ($ \mathrm{CO} $): Hemoglobin exhibits its highest affinity for $ \mathrm{CO} $, approximately 200-300 times greater than for $ \mathrm{O_2} $. This potent binding severely impedes oxygen transport in the presence of $ \mathrm{CO} $. Carbon dioxide ($ \mathrm{CO_2} $): Hemoglobin binds $ \mathrm{CO_2} $ to form carbaminohemoglobin, but with a significantly lower affinity than for $ \mathrm{CO} $. Oxygen ($ \mathrm{O_2} $): Hemoglobin's affinity for $ \mathrm{O_2} $ is lower than for both $ \mathrm{CO_2} $ and $ \mathrm{CO} $. Consequently, the affinity order is: \[ \mathrm{CO}>\mathrm{CO_2}>\mathrm{O_2}. \]

Arrange the affinity of hemoglobin (Hb) towards \( \mathrm{CO} \), \( \mathrm{CO_2} \), and \( \mathrm{O_2} \) in increasing order.
