Question

a specialized protein in saliva breaks up starch molecules in food into smaller chains of simple sugars. in this reaction, which molecule is the enzyme, which is the substrate, and which is the product? one of the four answer choices will not be used. answer bank: the specialized protein, the starch molecules, the saliva, the small chains of simple sugars. enzyme substrate product

Explanation:

Enzymes are specialized proteins that catalyze chemical reactions. In saliva, amylase (the specialized protein) acts on starch (the substrate) to break it down into smaller chains of simple sugars (the product). Saliva is just the medium where the enzyme is present and is not the enzyme, substrate, or product.

Answer:

Enzyme: the specialized protein
Substrate: the starch molecules
Product: the small chains of simple sugars
