Quizplus · Accepted Answer

If enzyme A is a repressible enzyme, it means that its activity can be inhibited by the presence of a corepressor. In this figure, compound C is shown to bind to the corepressor, indicating that it is involved in inhibiting the activity of enzyme A. Therefore, the best choice is E, as compound C would bind to the corepressor.
