A patient's small intestine exhibits reduced expression of cholecystokinin (CCK) receptors, specifically affecting digestive processes. Which consequence follows regarding bile secretion and fat digestion?

A)Increased bile acid reabsorption occurs
B)Pancreatic lipase activity increases drastically
C)Gastric emptying rate significantly decreases
D)Emulsification of fats will be impaired

💡 Explanation

Reduced CCK receptor expression impairs the signaling pathway for bile release from the gallbladder, because CCK stimulates gallbladder contraction. This directly reduces bile secretion, and therefore the emulsification of fats will be impaired, rather than alternative effects on lipase or gastric function.
