Exam 2 1. Below is an oxygen binding curve for a solution that contains 1 millimole of purified hemoglobin tetramer. Using the axes above, draw the curve you would expect if the solution contained 0.5 millimole of hemoglobin.
Curve is the same as the one shown.
You have discovered a mutant form of hemoglobin whose oxygen binding curve determined in intact red blood cells is shown below. For comparison, the oxygen binding curve for wildtype hemogobin in red blood cells is also shown. Affinity for BPG is increased in the mutant. Afffinity for BPG is decreased in the mutant. The stability of the R form is increased in the mutant.
