Hill plot of myoglobin and hemoglobin
WebNov 9, 2024 · Calculate the partial pressure of oxygen needed to reach 99% saturation in myoglobin. Calculate the fraction of oxygen sites bound in hemoglobin when the pO2 is only 5 torr; Calculate the fraction of oxygen needed to reach 80% saturation in hemoglobin. Before we begin, let’s define a few things: p50 of myoglobin = 2.8 torr. p50 of hemoglobin ... WebThe slope of the hill plot at the point of log(Y/(1-Y))= 0, the midpoint of binding is called the Hill Coefficient. Thus the Hill coefficient for myoglobin is 1. The Hill coefficient of 1 means that the oxygen atoms bind independently of each other. II Hemoglobin Hemoglobin (Hb) is a compact globular protein.

WebDec 22, 2024 · Thus the slope of the Hill equation is simply n . This is called the Hill coefficient or n H . For myoglobin, its value is 1 because myoglobin does not bind cooperatively to O 2. For HbA, however, it is 2.8. The higher the n H , the more sigmoidal the kinetics of the reaction under study. WebD) It results in a nonlinear Hill Plot. E) It results in a sigmoidal binding curve. 11. Reversible binding of a protein to a ligand: oxygen-binding proteins Pages: 168-169 Difficulty: 1 Ans: D Carbon monoxide (CO) is toxic to humans because: A) it binds to myoglobin and causes it to denature. B) it is rapidly converted to toxic CO2.
