Verified step by step guidance1
Understand that amylase is an enzyme that catalyzes the breakdown of certain macromolecules in the diet.
Recall the four main types of dietary macromolecules: proteins, carbohydrates (including starch and cellulose), lipids (such as triglycerides), and nucleic acids.
Recognize that amylase specifically targets carbohydrates, not proteins or lipids.
Identify that starch is a polysaccharide carbohydrate composed of glucose units, which amylase breaks down into simpler sugars.
Conclude that amylase digests starch, making it the correct answer among the options provided.
