Zymogen activation by paial proteolysis is an example of
Allosteric modification
Enzyme induction
Enzyme repression
Covalent modification
The activity of enzymes may be increased or decreased by covalent modification. It means, either the addition of a group to the enzyme protein by a covalent bond; or removal of a group by cleaving a covalent bond. Zymogen activation by paial proteolysis is an example of covalent activation. Addition or removal of a paicular group brings about covalent modification of enzyme protein. This is a reversible reactionRef: DM Vasudevan, Page no: 56
