SOLVED:Demand rules for phosphorylation: Proteins in the cell can be activated by phosphorylation, in which a phosphoryl group is added to a specific site on the protein. We will call such proteins phospho-active. Other proteins are inactivated by a phosphorylation event, and we will call these phospho-inactive. Phosphoryl groups are added by kinases, and removed by phosphatases. a. Develop demand rules to predict when a phospho-active versus a phospho-inactive design is best. b. How does the an
