| List I | List II |
| (A). Rennin | (I). Fats emulsification |
| (B). Bile salts | (II). Enhances action of goblet cell |
| (C). Brunner's glands | (III). Hydrochloric acid |
| (D). Oxyntic cells | (IV). Curdling of milk |
Choose thecorrectanswer from the options given below:
Options:
Answer:
Solution:
Rennin is a proteolytic enzyme found in the gastric juice of infants which helps in the digestion of milk proteins by causing the curdling of milk. Thus, (A) matches with (IV).
Bile salts, such as sodium glycocholate and sodium taurocholate, are present in bile and help in the emulsification of fats, breaking them down into smaller micelles. Thus, (B) matches with (I).
Brunner's glands are located in the submucosa of the duodenum. They secrete an alkaline mucus that protects the duodenal mucosa from the acidic chyme and enhances the action of goblet cells. Thus, (C) matches with (II).
Oxyntic cells, also known as parietal cells, are found in the gastric glands and secrete hydrochloric acid (HCl) along with Castle's intrinsic factor. Thus, (D) matches with (III).
The correct matching is (A) - (IV), (B) - (I), (C) - (II), (D) - (III).
Answer: (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
