Which one of the following hormones converts excess of glucose into glycogen?
A. Glucagon - The pancreas releases glucagon when the concentration of insulin (and indirectly glucose) in the bloodstream falls too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High blood glucose levels, on the other hand, stimulate the release of insulin.
B. Thyroxine - It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.
C.Insulin - It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones.
D.Adrenaline - hormone increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximize blood glucose levels (primarily for the brain).
So, the correct option is ‘Glucagon’.
