Question

What purpose does saliva serve in digestion?

breaks down fats

breaks down complex carbohydrates

breaks down proteins

breaks down fiber

Answer 1

Saliva primarily serves to break down complex carbohydrates in the process of digestion. It contains the enzyme amylase, which begins the process of starch digestion by breaking down complex carbohydrates into simpler sugars. While saliva aids in the formation of a food bolus and helps with swallowing, it does not significantly break down fats, proteins, or fiber.
