Which of the following statements about enzymes are true? Choose all that apply
a.) an enzyme yields a specific product, whereas a nonbiologival catalyst may produce more than one product, and side reactions may occur.
b.) generally, an enzyme is specific for a substrate. for example, thrombin catalyzes the hydrolysis of the peptide bond between Arg and Gly.
c.) a substrate must bind to the active site before a reaction occurs.
d.) reactions occur at the active site, which usually consists of a crevice on the surface of the enzyme
e.) nonbiological catalysts and enzymes tend to have a similar degree of reaction specificity.
Answer:
a) True
b) True
c) True (enzyme-substrate complex)
d) True
e) False. Nonbiological catalysts don’t show reaction specificity
