Use the following information to answer the question(s) below. A series of enzymes catalyze the reaction X→Y→ Z → A. Product A binds to the enzyme that converts X to Y at a position remote from its active site. This binding decreases the activity of the enzyme. With respect to the enzyme that converts X to Y, substance A functions as an allosteric inhibitor a competitive inhibitor the substrate an intermediate a coenzyme
