Nonclassical competitive inhibition involves ________.
A)binding of the substrate at both the active site and at the inhibitor site
B)binding of either the substrate to the active site or the inhibitor to its own binding site thus preventing the other from binding
C)binding of the inhibitor to the substrate followed by binding of this complex to the active site
D)chemical removal of the substrate from the active site by reaction with the inhibitor

Question

Quizplus · Accepted Answer

Nonclassical competitive inhibition occurs when the inhibitor binds to a distinct site on the enzyme, rather than the active site. The inhibitor and substrate are both able to bind to the enzyme, but they cannot both bind simultaneously due to steric hindrance. Therefore, the inhibitor prevents the substrate from binding by occupying its own binding site on the enzyme. This type of inhibition is also known as "antagonistic" inhibition.
