Aseries of enzymes catalyze the reactions in the metabolic pathway 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
a. an intermediate
b. a competitive inhibitor
c. an allosteric inhibitor
d. the substrate

The correct answer will be option-C

Explanation:

In the given question, product A can bind to the enzyme which can convert X to Y.

This product A can act as a non-competitive inhibitor which can attach to the site away from the active site. These compounds are known as allosteric inhibitors.

The allosteric inhibitors bind to the enzyme away from the active site and change the conformation of the protein which changes the conformation of the active site which prevent enzyme bind the substrate.

Thus, Option-C is the correct answer.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
