Match the lac genes with their enzymes & functions;

lac genes	Enzyme	Functions
lacZ	b-galactosidase	which rids the cell of toxic thiogalactosides that also get transported in by lacY.
lacY	thiogalactoside transacetylase	which cleaves the sugar lactose into galactose and glucose, both of which are used by the cell as energy sources
lacA	lactose permease	a protein that inserts into the cell membrane and transports lactose into the cell
