Regulation of a metabolic pathway by the final product of the pathway is termed

Question

Quizplus · Accepted Answer

End-product inhibition and negative feedback are synonyms for the regulation of a metabolic pathway by its final product. This process enables the maintenance of a stable balance of metabolites within a cell or organism by preventing overproduction of a substance that could be harmful or wasteful. The final product of a pathway acts as an inhibitor of one or more enzymes involved in the same pathway, thus reducing its activity and slowing down the production of the product. This mechanism is widespread in many metabolic pathways, including glycolysis, the Krebs cycle, and amino acid biosynthesis.
