Which statement is false about covalent modification?

A
It is reversible
B
It is slower than allosteric regulation
C
It uses the same enzyme for activation and inactivation
D
Phosphorylation is a common covalent modification
High-Yield Explanation
It uses different enzymes for activation and inactivation Enzyme which adds phosphate is protein Kinase Enzyme which removes phosphate is protein Phosphatase. ADDITIONAL INFORMATION ON COVALENT MODIFICATION Covalent modification is a long term regulation (by hormones). It is slower than allosteric regulation. It is reversible.
