WebThe ability of hemoglobin (Hb) to transport respiratory gases is directly linked to its quaternary structure properties and reversible changes between T (tense) and R (relax) … WebThus, by stabilizing the normally tense T-state, BPG makes hemoglobin less likely to bind oxygen in an attempt to release the strain. This mechanism is necessary, because the T state of hemoglobin is so unstable that the equilibrium lies very strongly in favor of the R state and little to no oxygen is released.
