In response to increased concentration of the final product of a metabolic pathway

Question

Quizplus · Accepted Answer

The final product of a metabolic pathway can act as an allosteric regulator of one of the enzymes in the pathway, typically the first or second enzyme. This feedback inhibition serves as a mechanism to prevent the overproduction of the final product. As the concentration of the final product increases, it binds to the allosteric site of the enzyme, causing a conformational change that reduces the activity of the enzyme. This decrease in enzyme activity slows down the pathway and reduces the production of the final product. Therefore, choice C is the best answer.
