Model Answer

The enzyme present in saliva (the fluid in the mouth cavity) is salivary amylase. It is produced by the salivary glands.

If the salivary glands stop secreting this enzyme, starch would not be broken down into simple sugars in the mouth. Digestion of carbohydrates would be delayed, beginning only from the small intestine.
