A) the final product of an enzyme -catalyzed reaction inhibits the rate -limiting enzyme via allosteric regulation.
B) the product of the rate -limiting step of an enzyme -catalyzed reaction inhibits the rate -limiting enzyme via covalent regulation.
C) the product of the rate -limiting step of an enzyme -catalyzed reaction inhibits the rate -limiting enzyme via allosteric regulation.
D) the initial substrate of an enzyme -catalyzed reaction inhibits the rate -limiting enzyme via allosteric regulation.
E) the final product of an enzyme -catalyzed reaction inhibits the rate -limiting enzyme via covalent regulation.

Question

Quizplus · Accepted Answer

End-product inhibition typically involves the final product of an enzyme-catalyzed reaction pathway inhibiting an earlier step in the pathway through allosteric regulation, not covalent modification. This mechanism helps regulate the pathway and prevent the accumulation of unnecessary products.
