Explanation:

Amylase is a digestive enzyme secreted and is responsible for breaking down <u>starch.</u>

Digestion describes the intake, chemical and physical breakdown, absorption of nutrients and excretion of food.  Alpha amylase, an enzyme produced in the pancreas, is found in human saliva; it catalyzes the breakdown of starch into glucose

Further Explanation:

Food is chemically and mechanically broken down into into smaller particles. This begins in the mouth, where food is mechanically crushed by the teeth, and mixed with saliva to allow water based enzymes like lingual lipase and amylase to work;- it's then transported to the stomach via the esophagus.

Alpha amylase, an enzyme produced in the pancreas, is also found in human saliva; it catalyzes the hydrolysis, or breakdown of starch into glucose in the stomach as gastric amylase. Amylase acts on polysaccharides bonds at random points along the chain by splitting the α 1-4 glycosidic bonds.
