Figure 2

Diagrammatic representation of oxygen equilibrium curves of the lug worm, man, and hemoglobin Scuba. The effect of hydrogen ions, 2, 3-bisphosphoglycerate, and carbon dioxide (H++BPG +CO2) is to promote a right shift. If man had the hemoglobin of the lug worm (left shift), he would die of anoxia.
