WebIonizable side groups located in the active site must have a certain charge for the enzyme to bind its substrate. Neutralization of even one of these charges alters an enzyme’s catalytic activity. An enzyme exhibits maximum activity over the narrow pH range in which a molecule exists in its properly charged form. WebAllostery and enzyme regulation Allostery is the change in the kinetic properties of an enzyme caused by binding to another molecule. The binding of a small molecule to the …

Enzymes can be regulated by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors. How do you control enzymatic reactions?
Webcentration , which can be regulated either by the rate of enzyme synthesis or the rate of enzyme degradation . Introduction The majority of chemical reactions that occur in living organisms are catalysed by enzymes, and the catalytic activities of some of these enzymes are subject to metabolic regulation.
