Question

Which among the following ones is the stimulus for release of CCK-PZ hormone?

• A. Fat-rich food reaching the stomach
• B. Any kind of food reaching the duodenum, to inhibit gastic secretion
• C. Vitamin-B-rich diet
• D. Lipid-rich food entering duodenum

Answer 1

The correct option is D Lipid-rich food entering duodenum

CCK-PZ or Cholecystokinin is secreted by the stimuli of the presence of partially digested fat in the duodenum of the small intestine. Lipid-rich food in duodenum acts as a potent stimulator of the release of CCK in the gut by the enteroendocrine cells of the duodenum.

So, the correct option is 'Lipid-rich food entering duodenum'.
