Question

Why does BPG binding in erythrocytes selectively affect hemoglobin's oxygen activity in tissues but not in the lungs?

Accepted Answer

BPG binds to the t state in tissues, which is not present in the r state in the lungs.

BPG binds equally in both tissues and lungs, affecting oxygen activity similarly.

Answer
