Question

Name the gene product required for metabolism of lactose

Answer 1

Answer:

The gene product of lacZ is β-galactosidase which cleaves lactose, a disaccharide, into glucose and galactose. lacY encodes Beta-galactoside permease, a membrane protein which becomes embedded in the cytoplasmic membrane to enable the cellular transport of lactose into the cell.

Answer 2

The lactose operon (lac operon) is an operon required for the transport and metabolism of lactose in E. The gene product of lacZ is β-galactosidase which cleaves lactose, a disaccharide, into glucose and galactose
