Question

Draw and annotate oxygen dissociation curves to show the effect of partial pressure of CO2 on the shape of the curve.

Accepted Answer

C - high CO2, low O2A - low CO2 high O2This happens bc H+ ions from carbonic acid compete with O2 to occupy Hb, decreasing affinity of Hb for O2High CO2 therefore cause Hb to unload O2
