Reaction catalyzed by lactase

Lactase hydrolyzes lactose into glucose and galactose. galactose is then converted to another glucose by galactosidase. How would I state the reactions involving these enzymes using word equations?

i need word equations with descriptions

for ex.
for ex.
combustion of propane to produce carbon dioxide and water is:
C3H8 + 5O2 --> 3CO2 + 4H2O
Propane (Fuel) + Oxygen --> Heat + Water + Carbon Dioxide
