Question

Draw and annotate graphs for oxygen dissociation curves for organisms that live in relatively low partial pressures of oxygen and for organisms with high oxygen demands. Explain value of the shape of the curve to the organism.

Accepted Answer

Llama (low partial pressure) - shift to left bc it needs higher affinity for oxygen in order to take in higher proportion of oxygen from atmosphereMouse (high oxygen demand) - shift to right bc it needs to be able to unload higher proporiton of O2 at higher partial pressure of O2
