Question

Question 1 0.5 pts Of the following, how could you determine whether a compound was an irreversible inhibitor of an enzyme? Compare enzyme activity in the presence and absence of the compound Compare enzyme activity in the presence of increasing amounts of the compound Compare enzyme activity with increasing amounts of substrate and the compound Compare enzyme activity in the presence and absence of the compound, then dilute each tested sample and repeat the activity assay. Question 2 0.5 pts Which of the following statements best describes a mixed (more like uncompetitive) inhibitor? An inhibitor that binds equally well to the free enzyme and the enzyme-substrate complex. An inhibitor that binds the free enzyme with higher affinity than the enzyme-substrate complex. An inhibitor that binds the enzyme-substrate complex with higher affinity than to the free enzyme. An inhibitor that binds to free enzyme active site and prevents substrate from binding.
