Among the following statements a, b, c, and d about enzymes are true.

An enzyme produces a single product, whereas a nonbiological catalyst may make several products and cause unintended side effects. An enzyme usually has a substrate for which it is specialized. For instance, thrombin helps the peptide link between Arg and Gly to be hydrolyzed.

Before a reaction takes place, a substrate needs to attach to the active site. The active site, which is typically a crevice on the enzyme's surface, is where reactions take place. Catalysts that are not biological do not exhibit reaction selectivity. Enzymes have a specific substrate preference. Chemical catalysis is less restricted and can use a variety of substrates to create a variety of products.
