Synthesis of an inducible enzyme requires
A)repressor alone bound to operator.
B)substrate bound to repressor.
C)substrate bound to promoter.
D)corepressor and repressor binding to operator.

Question

Quizplus · Accepted Answer

Inducible enzymes are synthesized when a specific substrate is present. The substrate binds to the repressor, causing a conformational change that prevents the repressor from binding to the operator. This allows RNA polymerase to transcribe the genes necessary for the synthesis of the enzyme.
