Hellow Some time dephosphorylation meaning activation and another time dephosphorylation meaning inhibition , so question : what determine this state and how ??

[@DrEliaHefner]

Depends on the enzyme, but typically enzymes in the same family are regulated in a similar fashion. The long answer is the presence or absence of a phosphoryl group changes the structure of the enzyme. The nature of the change dictates whether (de)phosphorylation activates or represses enzyme activity.
