Aseries of enzymes catalyze the reactions in a metabolic pathway represented as such: 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, product a functions as

An allosteric inhibitor.

Explanation:

An allosteric inhibitor binds to the enzyme at a site other than the active site and changes it conformation or charge in a way that reduces binding of substrates and thus reduces the enzymatic activity of the enzyme.

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.
