Essay

Refer to the figure showing the O₂-binding/dissociation curves for human and llama hemoglobins. South American camelids (i.e., llamas, alpacas, guanacos, and vicuñas) are native to the Andes Mountains.In the natural habitat of these mammals, more than 5,000 meters above sea level, the PO₂ is below 85 mm Hg, and the PO₂ in the camelids' lungs is about 50 mm Hg.The hemoglobins of these camelids are different from that of humans.Why would llama hemoglobin be advantageous at high altitudes?
