Salivary amylase is an enzyme found in the mouth. It breaks down starch into sugars. Why will salivary amylase NOT break down proteins? a. The enzyme is the wrong substrate for proteins. b. Only sugars have the correct shape to activate the enzyme. c. Proteins will not fit into the active site of the amylase enzyme d. Proteins do not have the proper active site for the enzyme to work on them

Answer : Option C) Proteins will not fit into the active site of the amylase enzyme

Explanation : Salivary amylase is the amylase that is found in the mouth. It breaks down the starch into sugars, but will not be able to break proteins as the proteins will not be fitting into the active site of the salivary amylase. So, it will not be able to break it down into amino acids.

It would be "C". You can actually spit in test tube and carry out digestion of starch in a test tube I did it in school for a science experiment and it was super gross.
