To add a phosphate group to an enzyme, a kinase is utilized; to remove the phosphate group, a phosphatase is utilized. explain why separate enzymes are used for each step, both from a thermodynamic and from a regulatory standpoint

Solution

To add a phosphate group to an enzyme, a kinase is utilized; to remove the phosphate group, a phosphatase is utilized. From a regulatory point of view, this is very much needed so as to get the appropriate signaling wherever needed for example in cell cycle. By adding and removing phosphate group different enzymes activate and deactivate various crucial proteins at different checkpoints in the cell cycle.

From thermodynamic standpoint:
