Ascientist discovers that a compound inhibits the action of an enzyme. what experiment can he perform to determine whether the compound is a competitive or noncompetitive inhibitor?

Answer

Raise the concentrations of the reactants to see if activity can be restored through reactant competition with the inhibitor for binding at the active site.

Explanation:

Competitive inhibitors have a structure similar to that of the normal substrate. Like the substrate, the inhibitor binds temporarily to the enzyme's active site but is not converted to products. This way, the inhibitor competes with the normal substrate for binding onto the enzyme's active site.

Non-competitive inhibitors do not compete with the normal substrate for the active site. They bind at a site different from the active site in a way that alters the structure of the active site. The result is that the normal substrate fails to bind to the active site.

is this a psat question, if so do not cheat try your best.
