polypeptide? - answer It will have lost its intermolecular forces between nitrogen and
hydrogen atoms

in enzyme kinetics? - answer It is dependent on activation energy from catalysis
What happens to the Vmax of an enzyme-catalyzed reaction when a competitive
inhibitor of the enzyme is added? – answer Vmax does not change
