When the level of glucose in the environment is low, abundant cyclic adenosine monophosphate (CAMP) binds the catabolite activator protein (CAP) to form the CAP-CAMP complex, which binds DNA. When CAP-CAMP binds DNA, the efficiency of RNA polymerase binding is increased at the lac operon promoter, which increases transcription of the structural genes. However, when glucose levels are high, the CAP-CAMP complex does not form and RNA polymerase cannot bind to the promoter efficiently. Low glucose P, lacl CAP CAP CAP RNA polymerase inducible cannot determine repressible lacP laco RNA polymerase laco Is the lac operon inducible or repressible? lacZ lacy lacA High glucose Continued below Is the lac operon inducible or repressible? inducible cannot determine repressible What type of protein regulates structural-gene expression as a result of glucose level? repressor activator cannot determine What type of overall gene regulation occurs as a response to glucose level? positive negative neither Continued below..
