What may be one reason that many of the enzymes in pancreatic juice are inactive in the pancreas, only to be activated once they enter the small intestine?
A
Protects the enzymes from degrading.
B
Decreases the total amount of enzymes needed.
C
Allows the digestion process to happen faster.
D
Prevents enzymes digesting tissues of the pancreas.
Verified step by step guidance1
Understand the role of pancreatic enzymes: Pancreatic enzymes are crucial for digestion, breaking down proteins, fats, and carbohydrates in the small intestine.
Recognize the importance of enzyme activation: Enzymes are often produced in an inactive form to prevent them from digesting tissues where they are synthesized, such as the pancreas itself.
Identify the mechanism of activation: These enzymes are activated in the small intestine by specific conditions or other enzymes, ensuring they function only where needed.
Consider the protective aspect: By remaining inactive in the pancreas, these enzymes prevent potential damage to pancreatic tissues, which could occur if they were active within the pancreas.
Relate to physiological safety: This mechanism is a protective strategy to ensure that the pancreas is not self-digested by its own enzymes, maintaining the integrity of pancreatic tissues.
