- RECALL Is there a connection between the free-energy change for a reaction and its equilibrium constant? If there is a connection, what is it?arrow_forwardREFLECT AND APPLY A model is proposed to explain the reaction catalyzed by an enzyme. Experimentally obtained rate data fit the model to within experimental error. Do these findings prove the model?arrow_forwardRECALL Show graphically how the reaction velocity depends on the enzyme concentration. Can a reaction be saturated with enzyme?arrow_forward
- REFLECT AND APPLY Would you expect an irreversible inhibitor of an enzyme to be bound by covalent or by non-covalent interactions? Why?arrow_forwardREFLECT AND APPLY What is the relationship between a transition-state analog and the induced-fit model of enzyme kinetics?arrow_forwardREFLECT AND APPLY Would you expect the reaction ATPADP+Pi to be accompanied by a decrease or increase in entropy? Why?arrow_forward
- REFLECT AND APPLY A reaction at 23C has G=1kJmol1. Why might this reaction become spontaneous at 37C?arrow_forwardRECALL What is a suicide substrate? Why are they important?arrow_forwardREFLECT AND APPLY Sulfanilamide and related sulfa drugs were widely used to treat diseases of bacterial origin before penicillin and more advanced drugs were readily available. The inhibitory effect of sulfanilamide on bacterial growth can be reversed by p-aminobenzoate. Suggest a mode of action for sulfanilamide.arrow_forward
