Enzymes and Starch Digestion

Amylase is an enzyme that breaks down starch into sugars.

• True

• False

Answer explanation

Amylase is indeed an enzyme that catalyzes the breakdown of starch into simpler sugars, confirming that the statement is true.

Diastase is not related to the breakdown of starch. True or False?

• True

• False

Answer explanation

False is correct because diastase refers to enzymes that break down starch into sugars, indicating a direct relationship with starch breakdown.

Salivary glands produce amylase to aid in digestion.

• True

• False

Answer explanation

True. Salivary glands secrete amylase, an enzyme that breaks down starches into sugars, aiding in the digestion process right from the mouth.

Starch is a protein that enzymes break down into amino acids.

• True

• False

Answer explanation

The statement is false because starch is a carbohydrate, not a protein. Enzymes break down starch into simpler sugars, not amino acids, which are the building blocks of proteins.

Enzymes are not specific to the reactions they catalyze.

• True

• False

Answer explanation

The statement is false because enzymes are highly specific to the reactions they catalyze, meaning each enzyme typically acts on a specific substrate or type of reaction.
