Which hormone causes dilation of blood vessels, increased oxygen consumption and glucogensis?

Options

A. ACTH
B. Insulin
C. Adrenaline
D. Glucagon

Answer

C

Explanation

Adrenaline (epinephrine) is a hormone produced by adrenal medulla and is secreted in great amounts during emotional states. It elevates the glucose level in blood steam (by glucogenesis) which is accompanied by increased in oxygen consumption, body temperature, heat production. Adrenaline also causes an increase in the flow of body by dilating the body vessels.
Insulin regulates the glucose level in blood.
ACTH (Adreno Corticotropic Hormone) is secreted by anterior pituitary and simulates the adrenal cortex.
Glucagon is a polypeptide hormone secreted by the alpha cells of islets of Langerhans of pancreas. It also acts to promte glycogenolysis.
