Verified step by step guidance

Understand the role of amylase: Amylase is an enzyme that catalyzes the breakdown of carbohydrates, specifically polysaccharides like starch, into simpler sugars such as maltose and glucose.

Recall the types of biomolecules: The major classes of biomolecules are carbohydrates, proteins, lipids, and nucleic acids. Each has specific enzymes responsible for their digestion.

Match the enzyme to the biomolecule: Amylase specifically targets carbohydrates, not proteins, lipids, or nucleic acids. This is because its active site is designed to bind carbohydrate molecules and hydrolyze glycosidic bonds.

Consider the digestion process: Amylase is secreted in saliva (salivary amylase) and the pancreas (pancreatic amylase). It begins carbohydrate digestion in the mouth and continues in the small intestine.

Conclude the answer: Based on the specificity of amylase for carbohydrates, the correct answer is carbohydrates.
