Given that all phosphotransferases have similar catalytic mechanisms, consider the half-reactions for the uncatalyzed transfer of inorganic phosphate from 1,3-BPG to ADP. One half-reaction produces water and the other consumes water. Observe that the phosphoglycerate kinase (PGK)-catalyzed phosphoryl transfer from 1,3-BPG to ADP does not include water. Select the best explanation for why the catalyzed reaction does not include water. uncatalyzed half-reaction 1 1,3-BPG + H2O → 3BPG + Pi uncatalyzed half-reaction 2 ADP + Pi → ATP + H2O PGK-catalyzed coupled reaction 1,3-BPG + ADP → 3PG + ATP
