Enzyme activation
conversion of an inactive form of an enzyme to one possessing metabolic activity. It includes 1) activation by ions (activators); 2) activation by cofactors (coenzymes); and 3) conversion of an enzyme precursor (proenzyme or zymogen) to an active enzyme.
Proteins have a crucial role in various biological activities. Get to know how proteins are able to perform as enzymes, cofactors, or regulators.
