If an E. coli cell is exposed to glucose, what happens? O A) CAMP levels are increased and the transcription of the lac operon is decreased due to a lack of CAP protein binding to its regulatory region. O B) CAMP levels are decreased, which does not allow the CAP protein to bind to its regulatory region. C) CAMP levels are increased and the transcription of the lac operon is also increased due to CAP protein binding. D) CAMP levels are decreased and the transcription of the lac operon is increased due to CAP protein binding.
