Answer :
Final answer:
In feedback inhibition, the accumulation of an end product of a metabolic pathway inhibits the pathway by allosteric regulation. This is a method to prevent overproduction by halting or slowing down the pathway.
Explanation:
In feedback inhibition, the accumulation of an end product of a metabolic pathway does not stimulate the pathway enzymes, nor does it have no effect. Instead, it inhibits the pathway by allosteric regulation. This is a method of controlling the metabolic pathway to prevent the overproduction of a substance. In this process, the end product of the metabolic pathway binds to an allosteric site, a location other than the active site, on one of the enzymes earlier in the pathway. This binding inhibits the activity of the enzyme and slows down or stops the entire pathway, thereby avoiding wasteful production of the end product.
