Final answer:
c) Acinar cells in the pancreas are responsible for storing and releasing digestive enzymes into ducts that lead to the pancreatic duct, contributing to the digestion of food in the small intestine.
Step-by-step explanation:
The cells of the pancreas that store and release digestive enzymes into ducts leading to the pancreatic duct are called acinar cells. These cells are part of the exocrine system of the pancreas and are responsible for secreting pancreatic juice containing digestive enzymes. This juice plays a crucial role in the digestion of food within the small intestine. The other cell types mentioned, such as alpha cells, beta cells, and islet cells, have endocrine functions. Specifically, alpha cells produce glucagon, beta cells produce insulin, and the islet cells are the collective term for the clusters that include alpha, beta, delta, and PP cells which secrete various hormones.
