Bernardo Alberto Houssay (Argentina) "for his discovery of the part played by the hormone of the anterior pituitary lobe in the metabolism of sugar" (April 10, 1887 – September 21,1971)

Carbohydrates produced from food or liver Used by muscles Production and consumption of carbohydrates-Constant blood sugar level The liver Hypoglycemia when liver is removed Hyperglycemia-the liver diminishes or ceases the production of sugar, and stores it.

The pancreas secretes insulin in adequate quantities so as to maintain a normal blood sugar level, and the blood sugar level regulates the amount of insulin secreted. Thus hyperglycemia increases the secretion of insulin and hypoglycemia diminishes or completely inhibits it.

He found that hypophysectomized dogs were hypersensitive to the toxic and hypoglycemic action of insulin These discoveries stimulated the study of harmonal feedback control mechanisms which are central to all aspects of modern endocrinology. endocrinology

Outline Carbohydrate metabolism and other metabolic processes are regulated by the balance maintained between the secretion of several endocrine glands. Diabetes and other metabolic diseases are a disturbance in this endocrine equilibrium.

Due to the body's ability to hold no more than around 2,000 kcal of glycogen, marathon runners commonly experience a phenomenon referred to as "hitting the wall" around the 20 mile (32 km) point of a marathon. (Approximately 100 kcal are utilized per mile, depending on the size of the runner and the race course.) When experiencing glycogen debt, runners many times experience fatigue.
