The process of end-product inhibition in a metabolic pathway is an example of a positive feedback loop.

Question

Quizplus · Accepted Answer

End-product inhibition is an example of negative feedback loop. This is because the end product inhibits the enzyme that catalyzes the reaction which leads to the production of the end product. This inhibition eventually results in the accumulation of substrates which leads to the restarting of the reaction. Thus, end-product inhibition negatively regulates the metabolic pathway. Positive feedback loops, on the other hand, amplify a signal and enhance the production of a product or its effect.
