5. If salivary amylase is lacking in the saliva, which of the following events in the mouth cavity will be affected?

(a) Proteins breaking down into amino acids

(b) Starch breaking down into sugars

(c) Fats breaking down into fatty acids and glycerol

(d) Absorption of vitamins

The answer is (b) Starch breaking down into sugars

Explanation: Salivary Amylase, a digestive enzyme, breaks down starch into simpler sugars and aids digestion. As a result, if salivary amylase is absent, starch breakdown will be hampered.
