A series of chemical reactions that completely oxidizes pyruvate to carbon dioxide, generating ATP, NADH, and FADH2. Also known as the citric acid cycle, it occurs in the mitochondrial matrix.
Named after German biochemist Hans Krebs, who elucidated this pathway in 1937 and won the Nobel Prize for his work in 1953. Originally called the citric acid cycle after the first compound formed in the process.
The Krebs cycle is like a molecular merry-go-round that never stops spinning - pyruvate jumps on, gets completely dismantled during the ride, and by the time it's done, all that's left is CO2 while the energy has been captured in molecular batteries!
Named exclusively for Hans Krebs (1900-1981); the cycle's full elucidation involved Krebs, Albert Szent-Gyorgyi, and others. Szent-Gyorgyi, a Hungarian biochemist, received 1937 Nobel Prize for work foundational to the cycle's understanding; cycle attribution primarily to Krebs.
Use 'Krebs cycle' (standard nomenclature); when teaching, credit both Krebs and Szent-Gyorgyi equally for citric acid cycle research contributions.

Albert Szent-Gyorgyi's foundational 1936-1937 research on biological combustion mechanisms preceded full Krebs cycle description; both scientists deserve recognition.
