APPLICATION SHORT ANSWER: Pepsin is an enzyme that is used in digestion which breaks down proteins
in stomach.
a. Does the breakdown of proteins occur in the mouth as well? __no___
b. Explain. Why or why not? In your answer use the terms that are associated with enzymes that
we discussed in class.
____Enzyme becomes denatured. Shape of the active site changes. The substrate won’t attach and the
products will not form.
