Question

Explain siliva, gastric juice and trypsin

Answer 1

Answer:

1.This lubricative function of saliva allows the food bolus to be passed easily from the mouth into the esophagus. Saliva contains the enzyme amylase, also called ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine.

2.One important component of gastric juice is pepsin. Pepsin is the chief digestive enzyme in the stomach that breaks down proteins. We see that chief cells produce pepsinogen (an inactive form of pepsin). Pepsinogen is converted to pepsin when the parietal cells found within the gastric glands secrete hydrochloric acid.

3.Tryptic digestion is a necessary step in protein absorption, as proteins are generally too large to be absorbed through the lining of the small intestine. Trypsin is produced as the inactive zymogen trypsinogen in the pancreas.
