Human Hemoglobin Sample

Normal Human Hemoglobin (HbA) P50 = 26 torr and the hill coefficientis N= 2.8

You have obtained the following oxygen binding curve data on a new sample of human hemoglobin.

A) Is this sample normal?

(This can be solved by visual inspection)

To answer this problem, you need to figure out the values of P50 and n (the Hill coefficient) for the new hemoglobin sample, then compare these to the values for normal hemoglobin.

P50 describes the partial pressure of oxygen at which half of the O2 binding sites are occupied. Theta represents the fraction ...
