Q.

If salivary amylase is lacking in the saliva, which of the following events in the mouth cavity will not take place properly
1 Proteins breaking down into amino acids  
2 Starch breaking down into sugars  
3 Fats breaking down into fatty acids and glycerol  
4 Absorption of vitamins

Amylase is a starch hydrolase enzyme that catalyses the conversion of starch to simple sugars. As a result, if salivary amylase is lacking in saliva, starch digestion is hampered.
