The following affect enzyme activity except

Regulation of Enzymes Can be classified as: Regulation of Enzyme Quality (Intrinsic Catalytic Efficiency) • Allosteric Regulation • Covalent modification. Covalent modification • Phosphorylation/dephosphorylation • Methylation • Adenylation • ADP ribosylation • Acetylation. Regulation of enzyme quantity Control of Enzyme Synthesis By Induction and Repression Control of Enzyme Degradation Enzymes are degraded by Ubiquitin—Proteasome pathway.
