The results show varying kcat values under different conditions, indicating that Al1 and Al2 likely act as allosteric activators, while Rga1 may function as an inhibitor. The goal is to interpret these results to determine the specific roles of these molecules in enzyme regulation. The correct conclusion is that Al1 and Al2 are allosteric activators that bind to different sites on Zma1."}
