Question

Match the following: 
I. Alpha (α) cells      [P] Glucagon 
II. Beta (β) cells       [Q] Somatostatin 
III. Delta (δ) cells     [R] Gastrin 
IV. G cells                [S] Proinsulin

• A. (I)-(P), (II)-(S), (III)-(Q), (IV)-(R)
• B. (I)-(Q), (II)-(S), (III)-(P), (IV)-(R)
• C. (I)-(R), (II)-(S), (III)-(Q), (IV)-(P)
• D. (I)-(S), (II)-(R), (III)-(Q), (IV)-(P)

Hint:

Remember: α-cells → Glucagon, β-cells → Insulin/Proinsulin, δ-cells → Somatostatin, G-cells → Gastrin. These are common GPAT questions on pancreatic and gastric hormones.

Answer 1

The Correct Option is A

Four pancreatic and gastric cell types need to be matched to the hormone each one produces. Taking them one at a time makes the correct combination clear.

1. Alpha cells: Secrete glucagon, which raises blood glucose by triggering glycogen breakdown and new glucose production in the liver. This pairs I with P.
2. Beta cells: Produce insulin, and proinsulin is the inactive precursor stored inside beta cells before it is processed into active insulin, so proinsulin is correctly tied to beta cells. This pairs II with S.
3. Delta cells: Release somatostatin, a hormone that suppresses the release of insulin, glucagon, and gastrin nearby. This pairs III with Q.
4. G cells: Found in the stomach lining, they secrete gastrin, which stimulates parietal cells to release stomach acid. This pairs IV with R.

Assembling these four pairs gives I-P, II-S, III-Q, IV-R.

So the correct answer is (I)-(P), (II)-(S), (III)-(Q), (IV)-(R).
