Hi! I had two questions:
1- 2,3 BPG allosterically binds to Hemoglobin changing it to its T state so it has lower affinity for oxygen.
I am confused on how the percent saturation of oxygen in the lungs is still able to reach 100% if Hb cannot bind to oxygen as readily?
2- Since fetal hemoglobin has a higher affinity to oxygen and it has low affinity for 2,3BPG how is it able to release oxygen to the tissues if it has such a high affinity for oxygen?
Thank you
