Which of the following digestive system structures releases amylase?

a. Duodenum

b. Gallbladder

c. Goblet cells

d. Salivary glands

The correct answer is D. The salivary glands release amylase.

Explanation:

Amylase, (more properly amylases, since there are several) is a hydrolase enzyme that has the function of catalyzing the hydrolysis reaction of bonds 1-4 between glucose units by digesting glycogen and starch to form glucose fragments (dextrins, maltose) and free glucose. In animals it occurs mainly in the salivary glands (especially in the parotid glands) and in the pancreas.
