Lactose

Answer 1

breakdown lactose...

Answer 2

Agreed ^ with @shrutipande9
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
