(b) The diagram on the right compares O2-dissoci- ation curves for human hemoglobins characterized by dif- ferent p50 values. If Ko2 represents the equilibrium disso- ciation constant for oxygen binding, e.g., Hb(02)n Hb + nO₂ show the relationship between Ko2 and p50. Assign one of the curves (a, b, . . . , e) that best approxi- mates the Ko2 of each of the mutant hemoglobins in the table above including HbA where Ko2 represents the equi- librium dissociation constant for oxygen binding. If no curve is present for any of the mutant hemogobins, state the rea- son why the mutant is not represented. Indicate on the graph where its p50 would lie.
