Web24 dec. 2024 · Cells have evolved to use feedback inhibition to regulate enzyme activity in metabolism, by using the products of the enzymatic reactions to inhibit further enzyme activity. Metabolic reactions, such as anabolic and catabolic processes, must proceed according to the demands of the cell. WebAway from the active site, enzymes can be either activated or inhibited when substances different than the substrate (heterotropic effectors) bind and induce different physical states (shapes, as it were) in an enzyme. These shifts alter the ability of the binding site to collect and hold substrate.
