Question

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

Explanation / Answer

a,c,d,e are true

b - nonbiological catalysts (like metal) do not show reaction specificity.
