List the substrate and the subunit product of amylase. _starch & maltose respectively__ 2. What effect did boiling and freezing have on enzyme activity? Why? How well did the results compare with your prediction?__Boiling caused amylase to be denatured‚ thus inactivating the enzyme. Freezing has no effect. The function of an enzyme is directly related
