Vedclass · Answer

(A) The presence of fats in the duodenum triggers the release of hormones such as $CCK$ (Cholecystokinin) and $GIP$ (Gastric Inhibitory Peptide).These hormones act on the stomach to inhibit gastric motility and slow down the rate of gastric emptying.This mechanism ensures that the small intestine has sufficient time to emulsify and digest the complex fat molecules.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Gastric emptying is slowest after a fat-laden meal containing a large number of triglycerides.
$R$: Fatty acids in chyme stimulate the release of both $CCK$ and $GIP$,which slow stomach emptying.
