Biology - Chemical Coordination and Integration Question with Solution | TestHub
Match the Column I with Column II:
| Column I (Cells of islet of Langerhans) | Column II (Action of hormone) |
|---|---|
| (A) Alpha cells | (I) Inhibits release of pancreatic juice |
| (B) Beta cells | (II) Glycogenolysis |
| (C) Delta cells | (III) Glycogenesis |
| (D) F-cells | (IV) Decrease in gastric secretion and motility of digestive tract |
Choose the correct answer form the following options
Options:
Answer:
Solution:
Alpha cells of the islets of Langerhans secrete the hormone glucagon, which increases blood glucose levels by stimulating glycogenolysis in the liver. Thus, A matches with II.
Beta cells secrete the hormone insulin, which decreases blood glucose levels by promoting glycogenesis (conversion of glucose to glycogen) in the liver and muscles. Thus, B matches with III.
Delta cells secrete somatostatin, which inhibits the secretion of insulin and glucagon, and also decreases gastric secretion and motility of the digestive tract. Thus, C matches with IV.
F-cells (or PP cells) secrete pancreatic polypeptide, which inhibits the release of pancreatic juice (exocrine secretion of the pancreas). Thus, D matches with I.
The correct matching is A-II, B-III, C-IV, D-I.
Answer: A-II, B-III, C-IV, D-I
