AP Bio Enzyme Quiz with Complete
Solutions
competitive inhibitor a substance that reduces the activity of an enzyme by entering an
active site in place of the substrate whose structure it mimics
noncompetitive inhibitor a substance that reduces the activity of enzymes by binding to a
location remote from the active site, changing the enzymes shape so that the active site no longer
effectively catalyses the conversion of substrate to product
allosteric regulation (control) the binding or a regulatory molecule to a protein at one site
that effects the function of the protein at a different site
endergonic reaction a non-spontaneous chemical reaction, in which free energy is
absorbed from its surroundings
exergonic reaction a spontaneous chemical reaction, in which there is a net release of free
energy
