Question 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

Solution

(b) Starch breaking down into sugars

Salivary amylase is the enzyme which breaks down starch into sugar in the mouth. Therefore, if salivary amylase is absent in saliva then starch will not be broken down into sugars.
