Which of the following scenarios would result in a relatively low energy of activation?
A)an enzyme binds to the substrate with greater affinity than the transition state B)an enzyme binds to both substrate and transition state with equal affinity C)an enzyme binds to the transition state with greater affinity than the substrate D)an enzyme binds only to the transition state E)none of the above
Since the product of the reaction catalyzed by hexokinase,glucose-6-phosphate (G6P),can act as both a competitive and uncompetitive inhibitor,what can be said about the interaction between G6P and hexokinase?
A)G6P binds only to active site of the enzyme B)G6P binds only to a regulatory site of the enzyme C)G6P binds to both the active site and a regulatory site of the enzyme D)G6P binds to one of the substrates,ATP,thus preventing ATP from binding to the active site E)none of the above
