Concept 11: The Effect of Glucose and Cyclic AMP on the lac Operon

The presence or absence of glucose affects the lac operon by affecting the concentration of cyclic AMP.

The concentration of cyclic AMP in E. coli is inversely proportional to the concentration of glucose: as the concentration of glucose decreases, the concentration of cyclic AMP increases.
