The enzyme hexokinase catalyzes the phosphorylation of glucose according to the reaction shown below.Glucosamine is a competitive inhibitor of hexokinase.Which of the following best describes the inhibition by glucosamine? 
A) Glucosamine stabilizes the active site of the enzyme,preventing glucose-6-phosphate from being released.
B) Glucosamine reacts with glucose,preventing it from binding to the active site of the enzyme.
C) Glucosamine binds to the active site of the enzyme,preventing glucose from binding.
D) Glucosamine binds to the surface of the enzyme,causing a change in the shape of both the enzyme and the active site,preventing glucose from binding.
E) Glucosamine reacts with glucose-6-phosphate,preventing it from being released from the active site.
