Which of the following hormones stimulates conversion of protiens into amino acids particularly during fasting or hibernation?

Glucocorticoids (such as cortisol) are catabolic hormones that stimulate proteolysis - the breakdown of proteins into amino acids, particularly during fasting, stress, or hibernation. These amino acids can then be used for gluconeogenesis to maintain blood glucose levels. Secretin stimulates digestive secretions, adrenalin (epinephrine) is primarily involved in acute stress response, and enterogastrone inhibits gastric secretions.
