Question

Which of the following cell secretes cholecystokinin hormone?

• A. Alpha cell
• B. Beta cell
• C. F cell
• D. I cell

Answer 1

The correct option is D I cell

• Cholecystokinin, officially called pancreozymin, is synthesized and secreted by enteroendocrine cells or I-cell in the duodenum, the first segment of the small intestine.
• Its presence causes the release of digestive enzymes and bile from the pancreas and gallbladder, respectively, and also acts as a hunger suppressant. Hence, I cell secretes cholecystokinin hormone.

So, the correct answer is 'I cell'.
