Which of the statements about enzymes are true? Generally, an enzyme is specific for a particular substrate. For example, thrombin catalyzes the hydrolysis of the peptide bond between Arg and Gly. An enzyme yields a specific product, whereas a nonbiological catalyst may produce more than one product with the occurance of side reactions. Catalysis occurs at the active site, which usually consists of a crevice on the surface of the enzyme. Nonbiological catalysts and enzymes tend to have a similar degree of reaction specificity. A substrate must bind to the active site before catalysis can occur.

Answer: All the statements in this question are true, except that stating: "Nonbiological catalysts and enzymes tend to have a similar degree of reaction"

Explanation:

Enzymes are specific for a particular substrate. Chemical catalysis is not as specific and can use several substrates and produce different products
