Enzymatic activation
WebAn enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme surface). The combination formed by an enzyme and its substrates is called the enzyme–substrate complex. When two substrates and one enzyme are involved, the … WebEnzyme activation can be accelerated through biochemical modification of the enzyme (ie, phosphorylation) or through low molecular weight positive modulators. Just as with …

Enzymes' specificity comes from their unique three-dimensional … WebThe right part of this diagram shows allosteric activation. The allosteric activator binds to an enzyme at a site other than the active site. The shape of the active site is changed, allowing substrate to bind at a higher affinity. ... are often given the name of allosteric enzymes 2 …
WebHexokinase -I (HK-I) is an enzyme activator because it draws glucose into the glycolysis pathway. Its function is to phosphorylate glucose releasing glucose-6-phosphate (G6P) as the product. HK-I not only signals the activation of glucose into glycolysis but also maintains a low glucose concentration to facilitate glucose diffusion into the cell.
