The Cori cycle (also known as the lactic acid cycle), a metabolic pathway in which lactate produced by anaerobic glycolysis in muscles is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.

In 1947 Carl Cori and his wife Gerty Cori (1896-1957) shared the Nobel Prize (with Houssay) “for their discovery of the course of the catalytic conversion of glycogen.”  They are more often remembered for the Cori cycle (see No. 12327).
