Destruction of all beta cells in the pancreas would cause:
Correct answer: C. Insulin secretion to stop and an increase in blood glucose
- A. Glucagon secretion to stop and a decrease in blood glucose
- B. Glucagon secretion to stop and an increase in blood glucose
- C. Insulin secretion to stop and an increase in blood glucose
- D. Insulin secretion to stop and a decrease in blood glucose
Explanation
The beta cells produce insulin, which lowers blood glucose. Without insulin, glucose remains high, leading to hyperglycemia.

About Chemical Coordination and Hormones
Chemical coordination uses hormones released by endocrine glands and carried in blood to specific target cells. Coverage includes the pituitary, thyroid, pancreas, adrenal glands, ovaries and testes, feedback control, and the contrast between slower, longer-lasting hormonal responses and rapid nervous coordination.
