Question

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

Explanation:

• For "Salivary amylase specifically binds to amylose": The diagram shows salivary amylase (enzyme) binding to amylose (substrate), so this is true.
• For "An enzyme speeds up a chemical reaction": Enzymes are biological catalysts that increase the rate of chemical reactions, so this is a fundamental property of enzymes and is true.
• For "Salivary amylase is used up during a chemical reaction": Enzymes are not used up in reactions; they can be reused, so this is false.
• For "Salivary amylase helps build polymers like proteins": Salivary amylase breaks down starch (a polysaccharide) into small sugars, it does not build proteins (proteins are built by ribosomes with different enzymes/mechanisms), so this is false.

Answer:

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