Answer the following questions in regards to the lac operon under the following conditions. cAMP levels are very low. Lactose is present.
1) Are glucose levels high or low?
2) Is the repressor active or inactive?
3) What (or Why is it) activated/inactivated the repressor?
4) Is the CAP active or inactive
5) How much transcription would occur at the lac operon? Here you only need to say no transcription OR limited transcription OR high transcription.

cAMP levels are Low when glucose is the main carbon source, hence does not activate the lac operon.

1) Glucose levels are high, given Low amounts of cAMP present.
2) Repressors are inactive.
3) lac repressors bind to allolactose, an analogue of lactose in the presence of lactose and is inactivated, aka unable to bind to the lac operator.
4) the CAP is inactive as Low amounts of cAMP binds to CAP to activate it
5) Limited transcription will occur. As the main source of energy is from glucose, metabolism of lactose is not prioritised in the presence of glucose
