The results indicate that Al1 enhances enzyme activity significantly, suggesting it may act as an allosteric modulator, while Rga1 does not improve activity, indicating it may be an inhibitor. The task is to analyze these results and select the correct interpretation of the roles of Al1 and Rga1 from the provided options."}
