An inhibitor binds to a site other than the active site of the enzyme.Which statement below correlates with this observation?
A)It must be a competitive inhibitor.
B)The inhibition must be irreversible.
C)It could be noncompetitive or uncompetitive inhibition.
D)It could be irreversible,competitive,noncompetitive or uncompetitive.The data do not relate to the type of inhibition.

Quizplus · Accepted Answer

Noncompetitive or uncompetitive inhibition can occur when the inhibitor binds to a site other than the active site of the enzyme. Competitive inhibition, on the other hand, occurs when the inhibitor binds to the active site and competes with the substrate for binding. The statement rules out irreversible inhibition, as it suggests that the inhibition is reversible. Additionally, the statement does not provide any information on whether the inhibition is reversible or not. Therefore, option C is the best choice.
