Question

1. What is the function of pancreatic juice .

2.Name the gastric juice secreted by gastric gland and write its function.

Answer 1

Answer:

1.Pancreatic juice neutralizes gastric juice to provide optimal pH for enzymes to function. Pancreatic enzyme functions are listed in Table 10.10. Chyme in the duodenum causes the release of the hormone secretin, which induces the pancreas to produce large volumes of fluid rich in bicarbonate, but lacking in enzymes.

2.Pepsinogen is converted to pepsin when the parietal cells found within the gastric glands secrete hydrochloric acid.

The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
