When an enzyme reaches its saturation point, it means that all of the enzyme's active sites are occupied by substrate molecules. Therefore, increasing the concentration of substrate will not increase the enzyme's reaction rate any further, as the enzyme is already working at maximum capacity. At this point, the amount of substrate becomes very high, leading to saturation.
