WebAug 3, 2024 · Enzymes are relatively larger than the substrates, whose only a small fraction is involved in catalysis by reducing chemical activation energy, also known as the catalytic site, and the other portion for binding with the substrate and orienting them also known as the binding site. ... Binding of the substrate(s) to the enzyme at their active ... WebWhen an enzyme binds its substrate, an enzyme-substrate complex is formed. This complex lowers the activation energy of the reaction and promotes its rapid progression in one of many ways. On a basic level, enzymes promote chemical reactions that involve more than one substrate by bringing the substrates together in an optimal orientation.

WebEnzymes are "specific." Each type of enzyme typically only reacts with one, or a couple, of substrates. Some enzymes are more specific than others and will only accept one particular substrate. Other enzymes can act on a range of molecules, as long as they contain the type of bond or chemical group that the enzyme targets.
