Digestive enzymes are secreted by different exocrine glands including: 1  Salivary glands.2  Secretory cells in the stomach.he enzymes that are secreted in the stomach are called gastric enzymes. The stomach plays a major role in digestion, both in a mechanical sense by mixing and crushing the food, and also in an enzymatic sense, by digesting it.
Enzymes are important in digestion. Digestion is the breakdown of carbohydrates, proteins and fats into small soluble substances that can be absorbed into the blood. Lipases and proteases are used in biological detergents, and enzymes are used in the manufacture of food and drink.igestion is the breakdown of large molecules into smaller, soluble molecules that can be absorbed into the body.
