Question

select the true statements. salivary amylase is used up during a chemical reaction. salivary amylase helps build polymers like proteins. salivary amylase specifically binds to amylose. an enzyme speeds up a chemical reaction.

Explanation:

• Enzymes, like salivary amylase, are not consumed in chemical reactions. They act as catalysts to speed up reactions.
• Salivary amylase breaks down starch (amylose is a component of starch), not build polymers like proteins. Proteins are built by processes involving ribosomes and amino - acid polymerization.
• Salivary amylase has a specific binding to amylose (a form of starch) due to its active - site structure.
• By definition, enzymes are biological catalysts that speed up chemical reactions.

Answer:

Salivary amylase specifically binds to amylose. An enzyme speeds up a chemical reaction.
