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

  1. Glucagon
  2. ACTH
  3. Insulin
  4. Adrenaline

Answer

(4) Adrenaline

Solution

As per NCERT, adrenaline (emergency hormone) increases alertness, pupillary dilation, piloerection, sweating, heart beat, strength of heart contraction and rate of respiration, and stimulates the breakdown of glycogen, resulting in an increased concentration of glucose in blood.

It dilates the blood vessels of skeletal muscles and heart, raises oxygen consumption (metabolic rate) and increases glucose formation.
