A kind of regulation whereby a shape change in one subunit of a protein caused by substrate binding is transmitted to all the other subunits, facilitating binding of additional substrate molecules to those subunits.Group of answer choicesfeedback inhibitionallosteric regulationcompetitive inhibitioncooperativit

A method of metabolic control in which the end product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway.Group of answer choicescooperativityfeedback inhibitioncompetitive inhibitionallosteric regulation

A substance that reduces the activity of an enzyme by binding to a location remote from the active site, changing the enzyme’s shape so that the active site no longer effectively catalyzes the conversion of substrate to product.Group of answer choicescompetitive inhibitornoncompetitive inhibitor

Noncompetitive inhibition of enzymes occursMultiple Choicewhen a substance other than the correct substrate binds at the active site of an enzyme.when a substance binds to an enzyme at a site away from the active site.by denaturation of an enzyme.by blocking the production of an enzyme.when two enzymes bind together.
