Read the following statements.
I. Glucocorticoids stimulate gluconeogenesis, lipolysis and proteolysis
II. Glucocorticoids inhibit cellular uptake and utilisation of amino acids.
III. Adrenaline and nor-adrenaline increase alertness, papillary dilation, piloerection, sweating
IV. Catecholamines stimulate the breakdown of glycogen resulting in an increased concentration glucose in blood
How many of the given statements are true?

The adrenal medulla of adrenal gland secretes two hormones called adrenaline or epinephrine and noradrenaline or norepinephrine. These are commonly called catecholamines. Adrenaline and noradrenaline are rapidly secreted in response to stress of any kind and during emergency situations and are called emergency hormones or hormones of Fight or Flight. These hormones increase alertness, pupilary dilation, piloerection (raising of hair), sweating etc. Both the hormones increase the heart beat, the strength of heart contraction and the rate of respiration. Catecholamines also stimulate the breakdown of glycogen, resulting in an increased concentration of glucose in the blood. In addition, they also stimulate the breakdown of lipids and proteins.
