Why are proteases secreted in an inactive state?

Proteases are secreted in an inactive state, known as zymogens or proenzymes, to prevent them from digesting proteins within the cells or tissues that produce them. This regulation ensures that proteolytic activity occurs only in specific locations and at controlled times, thereby protecting cellular structures and maintaining homeostasis. Activation typically occurs in the digestive tract or other designated areas, where their function is needed for processes like digestion or protein turnover.
