C) There is glucose but no lactose in the cell. D) The cyclic AMP and lactose levels are both high within the cell.

What causes lactose operon to transcribe?

CAP is only active when glucose levels are low (cAMP levels are high). Thus, the lac operon can only be transcribed at high levels when glucose is absent. This strategy ensures that bacteria only turn on the lac operon and start using lactose after they have used up all of the preferred energy source (glucose).

The lac operon (article) | Khan Academy
https://www.khanacademy.org/…/a/the-lac-operon
Glucose absent, lactose present: Strong transcription of the lac operon occurs. The lac repressor is released from the operator because the inducer (allolactose) is present. cAMP levels are high because glucose is absent, so CAP is active and bound to the DNA. CAP helps RNA polymerase bind to the promoter, permitting high levels of transcription.

The answer is b) the cyclic AMP and lactose levels are both high within the cell. Here are the reasons: The lac operon undergoes repression by the lac repressor, which is bound when lactose levels are low (remember the lac operon encodes a beta-galactosidase which breaks lactose down into glucose and galactose; why would you want to induce the operon if there isn’t any lactose?).

In the lac operon, if lactose is present, whic of the …

In the fuctioning of the lac operon. a. the repressor binds to the operator only in the presence of lactose. b. the enzymes to make lactose from glucose are induced by the presence of cyclic AMP. c. the operon is normally “off” because lactose is normally absent and the cells preferentially catabolize glucose

Lac Operon – an overview | ScienceDirect Topics
https://www.sciencedirect.com/…/biochemistry-genetics-and-molecular-biology/lac-operon
This operon is a genetic unit that produces the enzymes necessary for the digestion of lactose (Fig. 16-13). The lac operon consists of three contiguous structural genes that are transcribed as continuous mRNA by RNA polymerase. An operator sequence located at the 5′ end serves as a binding site for a repressor protein that blocks RNA polymerase.
