The correct Answer is:
To determine which enzymes are present in pancreatic juice, we will analyze the given options step by step. ### Step-by-Step Solution: 1. **Understanding Pancreatic Juice**: - Pancreatic juice is a digestive fluid produced by the pancreas. It contains several important enzymes that aid in the digestion of carbohydrates, proteins, and fats. 2. **Analyzing the First Option**: - The first option lists the following enzymes: - Trypsinogen - Chymotrypsinogen - Procarboxypeptidases - Amylase - Lipases - Nucleases - **Conclusion**: All these enzymes are indeed present in pancreatic juice. Trypsinogen, chymotrypsinogen, and procarboxypeptidases are involved in protein digestion, amylase aids in carbohydrate digestion, lipases help in fat digestion, and nucleases break down nucleic acids. 3. **Analyzing the Second Option**: - The second option includes: - Trypsinogen - Chymotrypsinogen - Procarboxypeptidase - Aminopeptidases - Amylases - Lipases - Nucleases - **Conclusion**: This option is incorrect because aminopeptidases are not secreted by the pancreas; they are produced by the glands of the small intestine. 4. **Analyzing the Third Option**: - The third option lists: - Trypsinogen - Chymotrypsinogen - Procarboxypeptidases - Aminopeptidases - Amylases - Lipases - Nucleases - Nucleotidases - Nucleosidases - **Conclusion**: This option is also incorrect for the same reason as the second option; aminopeptidases are not part of pancreatic juice. 5. **Analyzing the Fourth Option**: - The fourth option includes: - Trypsinogen - Chymotrypsinogen - Procarboxypeptidases - Amylases - Lipases - Papsinogen - Nucleases - **Conclusion**: This option is incorrect because papsinogen is secreted by gastric chief cells, not the pancreas. ### Final Answer: The correct answer is the **first option**, which includes trypsinogen, chymotrypsinogen, procarboxypeptidases, amylase, lipases, and nucleases.
