Original internet the lac operon works under two devices. the cell needs to lack glucose and need to be near lactose. the lac operon codes for the enzyme lactase that allows the cell to convert lactose into glucose and galactose for the cell to metabolize into energy. when glucose levels are high, camp has low levels and doesn't attach to the cap protein allowing the protein to attach to dna to transcribe the protein. when glucose levels are low an increased amount of camp is produced binding to the cap protein permitting the transcription of the gene. when there is no lactose, there is a repressor protein that is connected to the gene stopping the transcription but when lactose is present it attaches to the repressor protein releasing it from the gene allowing transcription. if you want this process to happen you need to have the presence of lactose and the absence of lactose.
