A) ACTH
B) Insulin
C) Adrenaline
D) Glucagon
Correct Answer: C
Solution :
Adrenaline (epinephrine) is a hormone produced by adrenal medulla and is secreted in great amounts during emotional stress. It elevates the glucose level in blood stream (by glycogenolysis) which is accompanied by increase in oxygen consumption, body temperature, heat production. Adrenaline also cause an increase in the flow of blood by dilating the blood vessels. Insulin regulates the glucose level in blood. ACTH (Adreno Corticotropic Hormone) is secreted by anterior pituitary and stimulates the adrenal cortex. Glucagon is a polypeptide hormone secreted by the alpha cells of islets of langerhans of pancreas. It acts to promote glycogenolysis.
