WebCompetitive inhibition. Inhibition. So the classic case of competitive inhibition: if there's some molecule that competes for the substrate at the active site, as we'll see this isn't the only form of competitive inhibition, but this is the one that you will most typically see in a textbook. So that's our enzyme again. WebIn biochemistry, allosteric regulation (or allosteric control) is the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site.. The site to which the effector binds is termed the allosteric site or regulatory site.Allosteric sites allow effectors to bind to the protein, often resulting in a conformational change and/or a …
