Quizplus · Accepted Answer

In a repressible enzyme system, the end product (in this case, Compound C) often acts as a corepressor. When it binds to a regulatory protein (repressor), it forms a complex that can bind to the operator region of an operon and inhibit the transcription of the genes required for its own synthesis. This feedback inhibition prevents the excess production of the end product. Compound C does not always result in excess (ruling out A) and does not directly bind to the enzyme (ruling out C), and since not all options are correct, D is also incorrect.
