Which statement about enzymes is not correct?
The tertiary structure of an enzyme, maintained by interactions such as hydrogen bonds and disulfide bridges, determines the shape of its active site.
Enzymes are stereospecific catalysts because their active sites are chiral.
A chiral enzyme will catalyze the reactions of both the (R)(R)(R) and (S)(S)(S) enantiomers of a substrate at identical rates.
Computer-aided molecular modeling can be used to design inhibitor drugs that fit precisely into the active site of a target enzyme.
