Question

Quizplus · Accepted Answer

CCK, or cholecystokinin, is a hormone that plays a key role in digestion and satiety. It is released when food enters the small intestine and helps signal the brain to feel satiated or full. One of its actions is to slow down the gastric emptying, making the stomach fill more quickly and stay full longer, which helps in promoting the feeling of fullness or satiety. This contradicts options A, B, and D, as they describe speeding up digestion, affecting glucose uptake, and facilitating stomach emptying, respectively, which are not directly related to how CCK promotes satiety.
