Question

are secreted by the adrenal gland in response to stress and they promote the synthesis of glucose from non-carbohydrate substrates.

• A. Glucagon
• B. ACTH
• C. Insulin
• D. Glucocorticoids

Answer 1

The correct option is D Glucocorticoids

Glucocorticoids are secreted from the cortex region of the adrenal gland and it function to increase glucose levels in the blood.

Glucocorticoids stimulate gluconeogenesis or generation of glucose from fats and proteins in the liver. Glucocorticoids also stimulate the liver to produce the enzymes needed for gluconeogenesis. This generation of glucose from proteins is particularly important during very long periods of fasting or exercise when blood glucose levels might otherwise become very low.

Insulin and glucagon are secreted by the pancreas and these hormones regulate blood glucose levels.
ACTH is secreted by the anterior pituitary and stimulates the synthesis and secretion of steroid hormones called glucocorticoids from the adrenal cortex.
