Lactase catalyzes the breakdown of lactose. It would probably not catalyze the breakdown of starch because enzymes are SPECIFIC and are typically named for the substrate that it acts on. Amylase is the enzyme that catalyzes the breakdown of starch. (Named so because in plants, starch is stored in the amyloplasts)

Not likely. The beta-galactosidase protein that is made to cleave the glycosidic bond is specific to that operation and no others.

Each enzyme is specialized to aid a certain reaction. So only that specific enzyme can catalyze the break down of starch.
