Which enzyme in saliva helps break down starch?
Answer and explanation
Correct answer: Amylase
The governing concept is enzyme-specific digestion. Salivary glands release saliva, which contains amylase. In the mouth, this enzyme begins breaking complex starch into simpler sugars, such as maltose, under suitable conditions. Therefore option A is correct. Pepsin digests proteins mainly in the stomach, lipase acts on fats, and trypsin digests proteins in the small intestine, so these distractors do not match starch digestion by saliva.
