The Pancreatic Hormone That Causes Blood Sugar Levels to Fall

Question

The pancreatic hormone that causes blood sugar levels to fall is
A) cortisol.
B) somatotropin.
C) insulin.
D) glucagon.
E) aldosterone.

Accepted Answer

Insulin is the pancreatic hormone that causes blood sugar levels to fall by increasing glucose uptake by cells and promoting the storage of excess glucose as glycogen in the liver and muscles.

Other options are incorrect:
A) Cortisol is a steroid hormone released by the adrenal gland in response to stress, and it increases blood sugar levels by promoting gluconeogenesis.
B) Somatotropin, also known as growth hormone, can indirectly affect blood sugar levels by promoting lipolysis and increasing circulating free fatty acids, which can then be converted to glucose in the liver. However, it does not directly cause blood sugar levels to fall.
D) Glucagon is a pancreatic hormone that causes blood sugar levels to rise by promoting glycogenolysis and gluconeogenesis in the liver. 
E) Aldosterone is a steroid hormone released by the adrenal gland that regulates salt and water balance in the body, but it does not directly affect blood sugar levels.
