WebEnzymes are substrate specific, meaning that they catalyze only specific reactions. For example, proteases (enzymes that break peptide bonds in proteins) will not work on starch (which is broken down by the enzyme amylase). Notice that both of these enzymes end in the suffix -ase. This suffix indicates that a molecule is an enzyme. WebOn the answer line, write the letter of the correct choice. Over the din of traffic, we heard the extremely loud cry, "Extra!
