Fig. 19.9 Dioxygen binding curves for (I) myoglobin and for hemoglobin at various partial pressures of carbon dioxide (2) 20 mm Hg (3) 40 mm Hg (4) 80 mm Hg. Note that myoglobin has a stronger affinity for dioxygen than hemoglobin and that this effect is more pronounced in the presence of large amounts of carbon dioxide. [Modified from Bock. A. V. Field, H., Jr. Adair. G. S. J. Biol. Chem. 1924. 59, 353-378. Reproduced with permission.)...
