Subject: How does the levels of glucose affect the levels of cAMP in bacteria.

I mean when glucose levels are high the levels of cAMP are low, when the 
glucose levels are low, the levels of cAMP are high what are the details of 
this relationship metabolically.  I wrote earlier about this question, but I 
was given a eukaryotic explanation and not a prokaryotic one.  I understad how 
the lac operon works, but not the part about the glucose-cAMP relationship.  
Could you shed some light on this?  Are these glucose levels external or 
internal to the bacteria?  Thanks!
