Question

Quizplus · Accepted Answer

End-product inhibition occurs when the accumulation of a product of a metabolic pathway inhibits the activity of an enzyme involved in that pathway. As the concentration of the product reaches a certain level, it binds to the enzyme and reduces its activity. Therefore, increasing amounts of product reduce the activity of the enzyme.
