To protect the body.
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.
Proteases are secreted in their inactive forms so as to prevent self-digestion and the destruction of the body's own cells. This is because all cells have proteins and hence are susceptible to the catabolic effects of proteases. However, amylase is not secreted in an inactive form as we do not store starch in our cells, but rather, we store carbohydrates in the form of glycogen. Therefore amylase poses no risk to our cells. Lipase-secreting cells also do not contain lipids and therefore lipase poses no threat to the body's own cells.
Pepsinogen is an inactive form of the digestive enzyme pepsin. Almost all enzymes are proteins, and proteins are organic macromolecules.

The digestive enzymes secreted by the pancreas help to break down fats, proteins and starch molecules.
In the case of protein digesting enzymes, known as endopeptidases, such as those secreted in the stomach (pespin), it is obvious. If they were secreted active they would digest the glands which secrete the enzymes themselves (gastric glands). Instead they must be secreted in an inactive form, which once in the stomach and exposed to HCl acid and other pepsin enzymes the pepsinogen activates and begins digesting protein.
ANSWERAnimals digest their food. The proteins carbohydrates and fat in food. are broken down into simple molecules.
Five digestive enzymes that are secreted by the intestinal glands are peptidases, sucrase, maltase, lactase and intestinal lipase. These enzymes are important in the process of digestion.
because stomach has very high acid... so it will just denature the proteins.
Enzymes from the liver, pancreas and gallbladder are secreted into the small intestine to digest the food inside.
Digestive enzymes are produced by the pancreas and salivary glands in the body. Once produced, they are secreted into the gastrointestinal tract to help break down food particles into smaller molecules that can be absorbed by the body.
The digestive enzymes produced by the pancreas are typically produced as inactive precursors (zymogens). These inactive forms are activated in the digestive tract when specific proteases cleave them to their active forms, ensuring they are only active when needed for digestion.
