WebAlso, in a process called cooperativity, the substrate itself can serve as an allosteric activator: when it binds to one active site, the activity of the other active sites goes up. 3 ^{3} 3 cubed This is considered allosteric regulation because the substrate affects active sites far from its binding site.

In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate, the binding site, and residues that catalyse a reaction of that substrate, the catalytic site. Although the active site occupies only ~10–20% of the volume of an enzyme, it is the most important part as it directly catalyzes the chemical reaction. It usually con… Web• Define and explain allostery and the important physiological role of allosteric enzyme inhibition or activation. -the regulation of an enzyme by binding an effector molecule at a …
