What does you data indicate about the substrate concentration for lactase-catalyzed reaction?

Data typically indicate that the reaction rate for lactase-catalyzed reactions increases with substrate concentration up to a certain point, known as the saturation point. Beyond this point, all active sites of the lactase enzyme are occupied, leading to a plateau in reaction rate as the enzyme becomes saturated. This behavior follows Michaelis-Menten kinetics, where the reaction rate approaches a maximum velocity (Vmax) as substrate concentration increases. Thus, optimal substrate concentration is crucial for maximizing the efficiency of the lactase-catalyzed reaction.
