Now, as it turns out, two, three BPG is not the only allosteric effect. Therefore hemoglobin, there are two other molecules found inside our body, inside the red blood cells that can bind onto a special region of the hemoglobin other than the oxygen binding side and decreased affinity of hemoglobin for oxygen, thereby shifting the oxygen binding curve to the right side. And these two molecules are hydrogen ions and carbon dioxide. So once again, 23 BPG is not the only atmosphericic effect that improves the efficiency of hemoglobin. Hydrogen ions and carbon dioxide are also allosteric effectors that increase the amount of oxygen that is released by hemoglobin in the exercising tissues of our body. And this effect is known as the Bore effect.
