Multiple Choice

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?

Protects the enzymes from degrading.

Decreases the total amount of enzymes needed.

Allows the digestion process to happen faster.

Prevents enzymes digesting tissues of the pancreas.

Verified step by step guidance

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.
