When lactose is first introduced into the medium, the lac operon is not induced and thus permease isn't induced How is it possible for lactose to enter the cell before the lac operon is induced? a. While the lac operon is not induced yet there is low level expression most of the time which allows a small amount of permease to be expressed. This allows lactose to enter the cell at low levels. b. While the lac operon is not induced yet lactose enters the cell at low levels without any enzymes c. While the lac operon is not induced yet there is full level expression of the other operon which allows a sufficient amount of a permease-like enzyme to be expressed. This allows lactose to enter the cell d. While the lec operon is not induced yet there is full level expression most of the time which allows a sufficient amount of permease to be expressed This allows lactose to enter the cell
