Enzyme-rich pancreatic juice contains all the following except ________. nuclease amylase trypsin lipase pepsin

Break Down the Problem

1. Identify the components that are typically found in enzyme-rich pancreatic juice.
2. Discuss which enzyme is not produced by the pancreas.

Relevant Concepts

• Pancreatic Enzymes: The pancreas produces several enzymes that aid in digestion. These include:
  • Nuclease: Breaks down nucleic acids.
  • Amylase: Breaks down carbohydrates.
  • Trypsin: A protease that digests proteins.
  • Lipase: Breaks down fats.
  • Pepsin: A protease activated in the acidic environment of the stomach.

Analysis and Detail

• The enzymes nucleases, amylases, trypsin, and lipase are produced by the pancreas and are secreted as part of pancreatic juice.
• Pepsin, on the other hand, is not produced by the pancreas; it is secreted by the stomach in an inactive form (pepsinogen) and is activated in the acidic environment of the stomach.

Verify and Summarize

Reviewing the functions and origins of these enzymes, it is clear that all listed enzymes except pepsin are produced by the pancreas.

Final Answer

The correct answer is pepsin.
