What does amylase do?

Proteins into amino acids Starch into glucose Fats into fatty acids and glycerol Nucleic acids into nucleotides

Correct Answer:

Starch into glucose

Explanation:

Amylase is the digestive enzyme that acts on starch, a carbohydrate. It speeds up the breaking of starch by hydrolyzing the bonds that hold its glucose units together, producing smaller sugars such as maltose and, ultimately, glucose. In humans, this starts in the mouth with salivary amylase and continues in the small intestine with pancreatic amylase, with final steps turning the products into glucose that the body can use for energy. So, the function described here—turning starch into glucose—is what amylase does. Other enzymes handle proteins, fats, and nucleic acids.
