Lactase is a protein enzyme that digests (breaks down) lactose (milk sugar) into glucose and. galactose (smaller sugars). The chemical equation below illustrates what happens when the. enzyme lactase digests lactose (milk sugar).
Best Answer: B.Enzymes that brake down lactose. lac Z codes for b-galactosidase, which is an enzyme that cleaves b-galactosides (e.g. lactose). lac Y codes for permease, which is involved in the transport of b-galactosides into the cell. lac A codes for b-galactoside transacetylase, which acetylates b-galactosides. These are all enzymes involved in the breakdown/transport of lactose. Source(s): http://www.mikeblaber.org/oldwine/bch542...
