The word hydrolyze means to break down by the addition of H20, so the amount of H20 would decrease. Also, since the job of beta-galactosidase is to break down lactose, the amount of lactose will decrease in solution and the amount of monosaccharides would increase. Therefore, the amount of glucose and galactose would increase.
