Each step in the biochemical reaction A B C D is catalysed by a specific enzyme. Product D binds to the enzyme that converts B to C at a specific site that is not part of its active site. The binding of D to the enzyme decreases the activity of the enzyme. In this biochemical reaction, substance B functions as
