9. (2 pts) What is the common strategy by which catalysis occurs? A) increasing the probability of product formation B) shifting the reaction equilibrium C) stabilization of transition state D) All of the above. E) None of the above. 10. (2 pts) Allosteric modifiers alter the equilibria between: A) the ES state. B) the R and T forms of a protein. C) the forward and reverse reaction rate. D) the formation of a product and its reverse reaction. E) All of the above. 11. (2 pts) 2,3-bisphosphoglycerate: A) binds in the central cavity in the T form of hemoglobin. B) preferentially binds to deoxyhemoglobin and stabilizes it. C) is present in the red blood cells. D) All of the above. E) None of the above 12. (4 pts) The graph below shows the oxygen-binding curves for myoglobin and hemoglobin. a) Label the graph by using the 4 labels given. b) Use the curves to estimate the partial pressure of oxygen at 50% saturation for hemoglobin and myoglobin
