Verified step by step guidance

Understand the role of amylase: Amylase is an enzyme that catalyzes the breakdown of starch into simpler sugars, such as maltose and glucose. It is specifically involved in carbohydrate digestion.

Identify the macromolecule associated with starch: Starch is a polysaccharide, which is a type of carbohydrate. It is composed of long chains of glucose molecules linked together.

Eliminate incorrect options: Nucleic acids, lipids, and proteins are not carbohydrates. Amylase does not act on these macromolecules, as they require different enzymes for digestion (e.g., proteases for proteins, lipases for lipids, and nucleases for nucleic acids).

Match amylase to its substrate: Since amylase specifically digests starch, the correct macromolecule associated with amylase activity is starch.

Conclude the relationship: Amylase is the enzyme responsible for breaking down starch, a carbohydrate, into simpler sugars during digestion.
