(a) 2,3-Bisphosphoglycerate (BPG) reduces binding of O₂ to hemoglobin from almost hyperbolic to sigmoidal shape by stabilizing the T state. (b) CO2 is an end product of cellular respiration that is transported by Hb from tissue to lungs in the form of a carbamate moiety. (c) Four molecules of BPG bind to one molecule of hemoglobin. (d) Both H+ and CO₂ bind in a manner inversely related to the binding of O₂ (e) CO2 binds as a carbamate group to the a amino group at the amino terminal end of each Hb chain.
