WebPhosphorylation is a process that adds a phosphate group onto a protein to “activate” it—that is, to change its shape enough that it can function properly. a. Which step (s) in the phosphorylation cascade illustrated in Model 2 include phosphorylation? b. Where do the phosphate groups come from that are added to the proteins duringphosphorylation? WebPhosphorylation often acts as a switch, but its effects vary among proteins. Sometimes, phosphorylation will make a protein more active (for instance, increasing catalysis or …
