Feedback inhibition.
Explanation:
It is feedback inhibition pathway because it is a cellular control process in metabolic part wat in which the output of a metabolic pathway binds to an enzyme at the regulatory sites which is distinct from the active sites of the substrates, causing a conformational changes on the enzyme which then makes it to slow down or inhibit it's production or synthesis.
This help to prevents excess of the high levels of the product from accumulating in the cell
