A series of enzymes catalyse the reaction X Rightarrow Y Rig

A series of enzymes catalyse the reaction X Rightarrow Y Rightarrow Z Rightarrow 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. What is substance X? an allosteric inhibitor a substrate an intermediate the product With respect to the enzyme that converts X to Y, substance A functions as_. an allosteric inhibitor the substrate an intermediate a competitive inhibitor

Solution

x is initial substrate and A is the final product.. if e₁ is the enzyme mediated the reation from x to y( is main effective for regulating the pathway) then the final product A binds e₁ that leads to derease the activity of enzyme means inhibiting the reaction . so here x is a initial substrate. y and z are intermediate products.

substance A functions as an allosteric inhibitor beacuse when it is binds to enzyme it dereases the activity of enzyme by binding at active site.
