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 is called feedback inhibition, and is explained in this BiologyWise post. ipp recommandation hasWeballosteric control, in enzymology, inhibition or activation of an enzyme by a small regulatory molecule that interacts at a site (allosteric site) other than the active site (at which catalytic activity occurs). The interaction changes the shape of the enzyme so as to affect the formation at the active site of the usual complex between the enzyme and its … ipp printer server windowsFeedback inhibition is a cellular control mechanism in which an enzyme’s activity is inhibited by the enzyme’s end product.
