Secretin and cholecystokinin (CCK) are two hormones acting on the pancreas. While hydrochloric acid ( HCl ) from the stomach predominantly stimulates release of secretin, peptones are potent stimulators of CCK secretion. Fatty acids however, stimulate release of both secretin as well as CCK. Secretin results in pancreatic secretion of bicarbonate ions which helps to set the pH for optimal functioning of pancreatic di
Options
- AHCl would be required for optimal digestion of peptones.
- BCompared to HCl and fatty acids, peptones are less effective in stimulating release of secretin.
- CCompared to HCl , fatty acids are less potent stimulators of sodium bicarbonate secretion.
- DHCl and peptone are equally potent stimulators of digestive enzymes.
Correct answer
C. Compared to HCl , fatty acids are less potent stimulators of sodium bicarbonate secretion.
