D) promote CAP production
E) lead to CAP degradation

Question

Quizplus · Accepted Answer

In prokaryotes, high levels of cyclic AMP (cAMP) are present when glucose levels are low. This condition signals the cell to use alternative sources of carbon, such as lactose in the case of the lac operon. cAMP binds to CAP (catabolite activator protein), enabling CAP to bind to the DNA and facilitate transcription of genes necessary for the metabolism of other sugars.
