WebSupporting: 1, Contrasting: 1, Mentioning: 47 - An intriguing but controversial hypothesis has appeared that "The optimization of enzyme catalysis may entail the evolutionary implementation of chemical strategies that increase the probability of tunneling and thereby accelerate the reaction rate" (Kohen, A.; Klinman, J. P. Acc. Chem. Res. 1998, 31, 397). … WebThe following are true about enzymes: 1. an enzyme yields a specific product, whereas a nonbiological catalyst may produce more than one occurrence of the side reactions. 2. An enzyme is specific for a particular substrate, like thrombin catalyzes the hydrolysis of the peptide bond between Arg and Gly. 3.
