Vedclass · Accepted Answer

Permease

Vedclass · Answer

(C) In the $lac$ operon,the structural gene $lacY$ codes for the enzyme permease.Permease increases the permeability of the cell membrane to $\beta$-galactosides like lactose.Therefore,it is responsible for the active transport of lactose from the external medium into the cell.$\beta$-galactosidase $(lacZ)$ is responsible for the hydrolysis of lactose into glucose and galactose.Transacetylase $(lacA)$ transfers an acetyl group to $\beta$-galactosides.The repressor protein is encoded by the $i$ gene and regulates the transcription of the operon.
