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.
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.
