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. 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.

WebThe O 2 pressure at which half of the molecules in a solution of myoglobin are bound to O 2 (P 1/2) is about 1 mm Hg (1.3 × 10 −3 atm). Figure 4.2.2: Oxygen Binding to Myoglobin … WebThe shape of the Hill plot for hemoglobin suggests that Hb exists in two states: A low affinity form exists at low θ and low pO2 A high affinity form exists at high θ and high pO2 … dickies t shirt blackWebDec 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. dickies t shirt price philippines
