When glucose alone is present in a growth medium, one reason the lac operon of E. coli is not transcribed is because: promoter lacz B-galactosidase lacY permease lacA acetylase CAP regulator (activator) (repressor) terminator activator binding site operator CAMP (inducer) allolactose (repressor of regulator) RNA polymerase lactose is degraded before it can be converted to allolactose catabolite activator protein (CAP)/CAMP complex is not bound to the activator binding site and under these conditons RNA polymerase is unable to be recruited to the promoter none listed cyclic AMP is plentiful in the cell and inactivates RNA polymerase glucose binds to the repressor protein and prevents lactose from binding Which statement is NOT true about the repressor protein, in regard to the lac operon: promoter 1 lacz lacy B-galactosidase permease lacA acetylase CAP regulator (activator) (repressor) 1 operator activator binding site terminator CAMP (inducer) allolactose (repressor of regulator) RNA polymerase O is only expressed when glucose is present O binds to the operator region of the lac operon when glucose is being utilized All listed ARE true about the repressor O it changes its three-dimensional shape (conformation) when it is bound to the inducer, allolactose o it blocks transcription when it is bound to the operator
