Which of the following symptoms would you expect to observe in Tom? 17) In response to the hormone secretin, the pancreas secretes a fluid rich in bicarbonate ion. I8) In response to the hormone cholecystokinin, the pancreas secretes a fluid rich in enzymes.Explanation / Answer
12) 1. Pepsinogen - 5. Hydrochloric acid.
Pepsinogen is activated by hydrocholoric acid that are secreted by parietal cells and form active pepsin.
2. Trypsinogen - 4. Enteropeptidase.
Trypsinogen is activated by enteropeptidase.
3. Procarboxypeptidase - 6. Trypsin.
Carboxypeptidases or procarboxypeptidase are produced in an inactive form. Pro-carboxypeptidase is converted to its active form carboxypeptidase by the enzyme trypsin.
