The answer is CORTISOL. Cortisol is a glucocorticoid hormone, in humans, it is produced in the adrenal cortex of the adrenla gland. The hormone is usually released in response to low blood glucose concentration and stress. When the blood concentration is low, cortisol supply glucose to the body through the process of gluconeogenesis in the liver. Thus, the hormone helps to control blood sugar and to regulate metabolism.
