23) According to the induced fit hypothesis of enzyme catalysis, which of the following is CORRECT?

Question

A) The binding of the substrate depends on the shape of the active site.

B) Some enzymes change their structure when activators bind to the enzyme.

C) A competitive inhibitor can outcompete the substrate for the active site.

D) The binding of the substrate changes the shape of the enzyme's active site.

E) The active site creates a microenvironment ideal for the reaction.

Answer 1

The induced fit model of enzyme substrate binding suggests that they shape of the active site changes slightly when bound to substrate, so that it has a better "fit" to the molecule.

It seems as though you have homework or an assignment that you aren't doing on your own.  You could have easily found this answer by googling induced fit or looking it up in wikipedia.
