Question

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

• A. A-II, B-IV, C-I, D-III
• B. A-II, B-III, C-IV, D-I
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-III, C-II, D-I

Hint:

Alpha cells release glucagon and beta cells release insulin.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Each cell type of the islets secretes a different hormone.

Step 2: Match the pairs
Alpha cells secrete glucagon causing glycogenolysis, so A-II. Beta cells secrete insulin causing glycogenesis, so B-III.

Step 3: Remaining pairs
Delta cells secrete somatostatin, which lowers gastric secretion and gut motility, so C-IV. F-cells secrete pancreatic polypeptide, which inhibits pancreatic juice, so D-I.

Final Answer:
The correct matching is A-II, B-III, C-IV, D-I. \[ \boxed{\text{(B) }\text{A-II, B-III, C-IV, D-I}} \]
