what enzyme found in saliva breaks chemical bonds in starches, forming sugars?
amylase
chyme
pepsin
hydrochloric acid

Amylase.

Explanation:

Hello,

In this case, it is widely known that starch is composed by numerous glucose monomers by glucosidic bonds. In this manner, as glucose is needed by itself into the body, the enzyme amylase help us out to hydrolize starch (to break the chemical bonds binding glucose molecules into it) into individual glucose units. Such enzime is produced in the saliva.

Best regards.
