Which of the following best describes an example of how an enzyme inhibitor can work in a reaction catalyzed by an enzyme?

The enzyme inhibitor catalyzes the reverse reaction, which counteracts the work of the enzyme.
The enzyme inhibitor attacks and destroys the enzyme, which prevents the enzyme from helping in the reaction.
The enzyme inhibitor binds to the products of the reaction, which makes the work of the enzyme unproductive.
The enzyme inhibitor fits into the enzyme's active site, which prevents the enzyme from catalyzing the reaction.

cp123 · Answer

c. enzymes speed up reactions because of their shapes, so enzyme when enzyme inhibitors bind to the enzyme, the enzyme cannot do anything. It stops the work of the enzyme.
