Which enzymes initiate the digestion process?

The initiation of the digestion process begins in the mouth, where the salivary enzymes play a crucial role. Salivary amylase, produced by the salivary glands, is one of the key enzymes that starts breaking down carbohydrates contained in food into simpler sugars. This action sets the stage for further digestion as food moves along the digestive tract.

Other enzymes listed, such as lactase, primarily function later in the digestive process, specifically aiding in the digestion of lactose in dairy products. Pancreatic enzymes are involved in the later stages of digestion, occurring in the small intestine, where they help digest proteins, fats, and remaining carbohydrates but do not initiate the process. Alimentary, while related to the digestive system, refers to the entire digestive tract rather than a specific enzyme.

Thus, salivary enzymes are critical for beginning the digestive process, highlighting their importance in effective digestion right from the moment food enters the mouth.
