1. Name the components of gastric juice and write their functions.
2. Where is bile juice produced and what is its function ?

Dear student,
Please find below the answer:

1. The gastric juice contains hydrochloric acid, pepsin enzyme, and mucus. Their functions are as follows:-
a) Hydrochloric acid: It creates an acidic environment for the action of pepsin as well as kills the bacteria present in the food.
b) Pepsin: It begins the digestion of proteins into smaller molecules.
c) Mucus: It protects the stomach wall from hydrochloric acid.  

2. The bile juice is produced in the liver and is stored temporarily in the gall bladder.
Bile juice is a digestive juice secreted by the liver. Although it does not contain any digestive enzymes, it plays an important role in the digestion of fats. Bile juice has bile salts such as bilirubin and biliverdin. These break down large fat globules into smaller globules in the small intestine so that the pancreatic enzymes can easily act on them. This process is known as the emulsification of fats. Bile juice also makes the medium alkaline and activates lipase.

Hope this information clears your doubt.
Regards.
