Salivary amylase starts acting on which nutrient?
Answer and explanation
Correct answer: Starch
Salivary amylase is an enzyme secreted by the salivary glands and mixed with food in the mouth. Its substrate is starch, a complex carbohydrate. The enzyme begins hydrolysing starch into simpler sugars such as maltose, although digestion continues elsewhere in the alimentary canal. Therefore option A is correct; fats require lipases, proteins require proteases, and minerals do not need enzymatic digestion.
