The Bohr effect hinges around allosteric interactions between the hemes of the haemoglobin tetramer, a mechanism first proposed by Max Perutz in 1970. Haemoglobin exists in two conformations: a high-affinity R state and a low-affinity T state. When oxygen concentration levels are high, as in the lungs, the R state is favored, enabling the maximum amount of oxygen to be bound to the hemes. In the capillaries, where oxygen concentration levels are lower, the T stat… Webback in the lungs temp and PCO2 decreased and pH increases and changes to high affinity (left shift) summarize how pH, PCO2, temperature, and 2,3-BPG change the tertiary and quaternary structure of Hb and thus its O2 affinity. - CO2, H+, and 2, 3-BPG are charged/polar. - They attach to charged amino acids on the outside of Hb subunits.
