If compound C reacts with the allosteric site of enzyme A, it would exemplify feedback inhibition. This means that the end product of the metabolic pathway (compound C) binds to an allosteric site on the first enzyme (enzyme A) in the pathway, inhibiting its activity and preventing the pathway from continuing. This is a form of negative feedback regulation that helps to control the rate of the pathway and ensure that excessive amounts of the end product are not produced.
