Final answer:
Cholecystokinin (CCK) matches with the description (d) 'Stimulates release of bile,' as it promotes the secretion of pancreatic enzymes and bile necessary for fat digestion.
Step-by-step explanation:
The hormone that matches the description for gastric secretion is cholecystokinin (CCK), which fits description (d) 'Stimulates release of bile' as it stimulates the secretion of pancreatic enzymes and bile from the liver and release of bile from the gallbladder.
Cholecystokinin (CCK) is produced in the mucosal epithelium of the duodenum and has a critical role in facilitating digestion within the small intestine.
It is responsible for prompting the pancreas to secrete enzyme-rich pancreatic juice and for stimulating the gallbladder to release bile, which is important for fat digestion. By doing so, CCK aids in the digestive process by ensuring the proper breakdown of nutrients, particularly fats.
