Question

23
the salivary glands secrete the enzyme ________ that breaks down ________.
multiple choice

amylase, carbohydrates

pepsin, proteins

sucrase, sucrose

lipase; lipids

Explanation:

Salivary glands secrete salivary amylase. This enzyme initiates the digestion of carbohydrates (starches) in the mouth. Pepsin is secreted in the stomach (not salivary glands) and acts on proteins. Sucrase acts on sucrose but is mainly in the small intestine. Lipase (pancreatic lipase is more common for lipid digestion in the small intestine context here, and salivary lipase has a minor role compared to amylase's role in carbohydrate digestion in the mouth).

Answer:

amylase, carbohydrates
