Regulation of Enzymes
Can be classified as:
Regulation of Enzyme Quality (Intrinsic Catalytic Efficiency)
• Allosteric Regulation
• Covalent modification. 
Covalent modification
• Phosphorylation/dephosphorylation

Regulation of enzyme quantity
Control of Enzyme Synthesis
By Induction and Repression
Control of Enzyme Degradation Enzymes are degraded by Ubiquitin—Proteasome pathway.
