The part of the body that contains enzymes that break down starch molecules is the mouth.

Here's why:

* Salivary Amylase: The saliva in our mouths contains an enzyme called salivary amylase. This enzyme starts the process of breaking down starch molecules (long chains of sugars) into smaller sugar molecules.

* Digestion Continues: While the mouth begins the process, the breakdown of starch continues in the small intestine with the help of pancreatic amylase.
