Select one of the options below as your answer:



A.

B.
Enzymes that break down lactose




C.
Enzymes that synthesize lactose

Answer 1

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.
