1.
According to the Egyptian STEM biology syllabus, what is the exact scientific deduction regarding: Hormonal Regulation of Blood Glucose (Insulin and Glucagon)?
Alpha cells secrete insulin to elevate blood glucose levels
Glucagon is secreted by the adrenal cortex under stress
Beta cells of the islets of Langerhans secrete insulin to lower blood glucose by stimulating cellular uptake and glycogen synthesis, while alpha cells secrete glucagon to raise blood glucose by glycogenolysis
Insulin stimulates the breakdown of liver glycogen into glucose
