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 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 choicesnoncompetitive inhibitorcompetitive inhibitorNext
