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?

Question

Quizplus · Accepted Answer

The fact that G6P can act as both a competitive and uncompetitive inhibitor indicates that it can bind to both the active site and a regulatory site of the enzyme. If it only bound to the active site, it would only act as a competitive inhibitor. If it only bound to a regulatory site, it would only act as an uncompetitive inhibitor. Therefore, choice C is the best answer.

Since the Product of the Reaction Catalyzed by Hexokinase, Glucose-6-Phosphate
