Show answer and explanation
Correct answer: (D) Beta cells and alpha cells
Explanation
Pancreatic beta cells secrete insulin, while alpha cells secrete glucagon. Delta cells secrete somatostatin. The requested insulin-then-glucagon order therefore corresponds to D. The official key classifies this item as MSQ but contains the single correct selection D; that grading type is preserved.
