models for enzyme-substrate es complex formationthere are two popular models to explain the enzyme-substrate interaction these area fischers
group specificitysome enzymes prefer a specific functional group to be presenton the substrate molecules example- alcohol dehydrogenase
bond specificitysome enzymes act on a particular bond glycosidic peptide ester etc examples pepsin
reaction specificitysome enzymes catalyze only one reaction acting on a specific substrate example urease and
