Why is the presence of amylase in saliva important?
Answer and explanation
Correct answer: It starts changing starch into simpler sugar
The governing concept is enzyme-assisted carbohydrate digestion. Salivary amylase acts on starch, a complex carbohydrate, and begins breaking it into simpler sugars such as maltose while food is still in the mouth. This is why option A is correct and why carbohydrate digestion starts before food reaches the stomach. Amylase does not convert fat into bile, produce oxygen from protein, or filter blood; those claims describe unrelated processes.
