Cori cycle

(kō′rē)

[Carl Ferdinand Cori, Czech-born U.S. physician and biochemist, 1896-1984; Gerty T. Cori, Czech-born U.S. biochemist, 1896-1957]
The cycle in carbohydrate metabolism in which muscle glycogen breaks down, forms lactic acid, which enters the bloodstream and is converted to liver glycogen. Liver glycogen then breaks down into glucose, which is carried to muscles, where it is reconverted to muscle glycogen.
