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.

Why do the crystals of Bt toxin produced by some bacteria do not kill the bacteria themselves?
toxin is inactive: In bacteria, the toxin is present in an inactive form, called prototoxin, which gets converted into active form when it enters the body of an insect
What is the inactive from of the enzyme pepsin?
The inactive form of pepsin is called pepsinogen.
Why must protein-digesting enzymes be stored in the inactive form?
All the digestive enzymes are made of protein, yet some of them are protein-digesting enzymes. If they were all dumped into the same "pot" the protein digesting enzymes would quickly destroy the other enzymes, and the whole process would grind to a halt. The body must separate protein digestion from other processes.
What is the gastric enzyme that acts on proteins?
The proteolytic or protein eating enzyme of the stomach is called pepsin. Pepsin is secreted into the stomach as a zymogen (or inactive enzyme precursor) called pepsinogen which is converted into the active enzyme form by the hydrochloric acid and low pH in the gastric juices.
Why protein digesting enzymes are secreted in an inactive form in your body why it is not so incase of carbohydrate digesting and fat digesting enzymes?
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.
Where is trypsin released into?
Trypsin is a proteolytic enzyme, important for the digestion of proteins. In humans, the protein is produced in its inactive form, trypsinogen, within the pancreas.Trypsinogen enters the small intestine, via the common bile duct, where it converted to active trypsin.
Why pancreas is not digested by its own enzymes?
The acinar cells of the pancreas secrete proteolytic enzymes as zymogens or proenzymes. These enzymes are in their inactive form and must be activated by something else. One of these enzymes, trypsinogen, is activated by enterokinase found in the cells that make up the duodenum wall. Once activated to trypsin, it activates the other digestive enzymes.
Why are protein digestive enzymes produced and released in an inactive form?
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.
Is pepsinogen organic or inorganic?
Pepsinogen is an inactive form of the digestive enzyme pepsin. Almost all enzymes are proteins, and proteins are organic macromolecules.

What is the inactive from of the enzyme pepsin?
The inactive form of pepsin is called pepsinogen.
What are the main energy producing molecules provided by the Krebs cycle?
Energy Producing Catalytic molecules are Enzymes. The biochemical Energy produced by these enzymes is in the form of Atp.
Which organelle produces enzymes?
The lysosome of the cell produces digestive enzymes so as to break complex materials into simple ones for easy digestion.
Why must protein-digesting enzymes be stored in the inactive form?
All the digestive enzymes are made of protein, yet some of them are protein-digesting enzymes. If they were all dumped into the same "pot" the protein digesting enzymes would quickly destroy the other enzymes, and the whole process would grind to a halt. The body must separate protein digestion from other processes.
what does alcohol produce?
Alcohol is not fermented, it is produced by fermentation. The most common form of this is produced by the action of yeast enzymes: sugar --> alcohol + carbon dioxide
