The mechanism in which the end product of a metabolic pathway inhibits an earlier step in the pathway is most precisely described as
a) metabolic inhibition
b) feedback inhibition
c) allosteric inhibition
d) noncooperative inhibition

The correct answer is: B) feedback inhibition

This is an example of negative feedback: product of a process reduces the stimulus of the same process. It is the way of regulation in biological systems and the way the organism maintains its homeostasis (internal balance). Negative feedback is present in many biological processes such as regulation of blood sugar, temperature regulation, the actions of some enzymes..

d is the answer

sorry if its wrong!
