The correct Answer is:
To answer the question "Trypsinogen is activated by:", we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Trypsinogen**: - Trypsinogen is an inactive precursor (zymogen) of the enzyme trypsin, which is produced by the pancreas. 2. **Activation Process**: - Trypsinogen needs to be activated to become trypsin in order to perform its function in protein digestion. 3. **Identifying the Activator**: - The activation of trypsinogen occurs in the small intestine. The enzyme responsible for this activation is known as enterokinase (also referred to as enteropeptidase). 4. **Role of Enterokinase**: - Enterokinase is secreted by the intestinal mucosa and acts on trypsinogen to convert it into its active form, trypsin. 5. **Conclusion**: - Therefore, the correct answer to the question is that trypsinogen is activated by enterokinase. ### Final Answer: Trypsinogen is activated by enterokinase. ---
