"WebSo, what I know: 2,3 BPG decreases the hemoglobin oxygen affinity, making hemoglobin unload more O2 to the tissues. And also: 2,3 BPG can only bond to Deoxygenated hemoglobin, making hemoglobin''T state'' more stable, so it doesn't bond as much with O2. But that's my doubt: I can't really understand how 2,3 BPG bonding to deoxygenated … " - Bpg and hb

WebWhen it binds in a cavity made by the β chains, BPG shifts the equilibria from the oxyhemoglobin to the deoxyhemoglobin forms, thereby promoting the loss of O 2. 12. Why are myoglobin and hemoglobin highly colored red? Myoglobin and hemoglobin absorb green to yellow light in the 500 nm to 600 nm region of the spectrum. Red light is WebBPG is a byproduct of glycolysis. Because erythrocytes do not contain mitochondria, glycolysis is the sole method by which these cells produce ATP. BPG promotes the disassociation of oxygen from hemoglobin. Therefore, the greater the concentration of BPG, the more readily oxygen dissociates from hemoglobin, despite its partial pressure.
