WebIn biochemistry, metabolic pathways are activated and regulated in a variety of ways. One such method involves the inhibition of the entire pathway by the increased concentration of the end product. This process … WebThe feedback inhibition can be used to stop a synthesis reaction if there are too many products being formed by the synthesis. For instance, as the glutamine synthetase in E.coli continues to increase, the cumulative feedback inhibition would bind to an enzyme’s allosteric site, thus changing the enzyme’s formal form, and the glutamine ...
