Question

Felix has had problems with several hormone-regulated physiological processes. He has experienced hypoglycemia despite the administration of dextrose solution and glucagon. Control of Felix’s metabolic homeostasis has been largely disrupted by his endocrine disorder. Which of the following statements accurately describes how the adrenal gland is involved in the hormonal control of metabolic homeostasis?

a. Catecholamines control the metabolic rate during exercise, as the sympathetic nervous system increases catecholamine secretion from the adrenal medulla.

Explanation / Answer

Answer would be a. Catecholamines control the metabolic rate during exercise, as the sympathetic nervous system increase catecholamine secretion from adrenal medulla. Catecholamines are secreted during 'fight, fright, flight' and other states of stress. Common ones are epinephrine, norepinephrine. These are catabolic hormones and increase the level of glucose in blood via promoting glycogenolysis (breaking down glycogen in glucose) and gluconeogenesis ( making glucose from non-carbohydrate sources) while preventing insulin mediated glycogenesis.
