The substrate for amylase is primarily

Explanation:
Enzymes act on specific substrates, and amylase is the enzyme that targets carbohydrates, especially starch. It hydrolyzes the internal α-1,4 glycosidic bonds in starch, breaking it down into smaller sugars such as maltose and dextrins (and eventually glucose in later steps). That’s why starch is the primary substrate for amylase. Cellulose has a different linkage (β-1,4) and would require a different enzyme (cellulase); amylase won’t efficiently cleave those bonds. Proteins are the substrate for proteases that break peptide bonds, not for amylase. Glucose is a product of starch digestion, not the substrate that amylase acts on in this reaction.
