Answer:
HbA; lowers
Explanation:
The BPG in our blood stands for Bisphosphoglyceric acid. It is known as by its name as 2,3-Bisphosphoglyceric acid. It is present in our blood in the red blood cells. It binds with more affinity towards the de-oxygenated hemoglobin as compared to the oxygenated hemoglobin.
Hemoglobin in blood delivers oxygen to our tissues moire efficiently. It is abbreviated as Hb.
Thus BPG binds more tightly towards HbA or adult hemoblobin and which lowers the affinity for oxygen.
