Trypin Pepsin
Catalyzing Acceleration
PH
Trypsin and pepsin are both enzymes in the digestive system which catalyze the breakdown of proteins in food into smaller peptide
chains or into individual amino acids. However, like other enzymes, they differ in their substrate and optimal conditions. Select ALL
the statements that accurately describe the function of enzymes.
A)
Enzymes break down foods into smaller molecules in digestion.
B)
Enzymes increase the substrate concentration, increasing the reaction rate.
C)
Enzymes are not changed or used up in the reaction, but speed up the
reaction
Enzymes lower the activation energy, allowing the reaction to occur more
quickly
D)
Enzymes have a specific shape that allow them to bind to only one specific
E)
substrate
