Cholecystokinin (CCK) (iii) Acts on gastric glands D. Gastric inhibitory peptide (GIP) (iv) Acts on both pancreas and gall bladder Choose the correct answer from the options given below:
Options
- AA-(iii), B-(iv), C-(i), D-(ii)
- BA-(iii), B-(i), C-(iv), D-(ii)
- CA-(ii), B-(i), C-(iv), D-(iii)
- DA-(iii), B-(ii), C-(i), D-(iv)
Correct answer
B. A-(iii), B-(i), C-(iv), D-(ii)
Step-by-step solution
According to NCERT, the endocrine cells present in different parts of the gastro-intestinal tract secrete four major peptide hormones: 1. Gastrin acts on the gastric glands and stimulates the secretion of hydrochloric acid and pepsinogen. Hence, A matches with (iii). 2. Secretin acts on the exocrine pancreas and stimulates the secretion of water and bicarbonate ions. Hence, B matches with (i). 3. Cholecystokinin (CCK) acts on both the pancreas and gall bladder, stimulating the secretion of pancreatic enzymes and bi
