A Nobel Prize, of course. Such was the case for Hans Krebs, the biochemist who nabbed the award in 1953 for discovering the citric acid cycle, or “Krebs cycle”—the cellular pathway that converts ...

A second autotrophic pathway (Arnon–Buchanan cycle) uses a reductive citric acid cycle and is found in anaerobic or microaerophilic bacteria and archaea. A third autotrophic pathway (Wood ...

Prebiotic molecules central to life's earliest metabolic processes—chemical reactions in cells that change food into ...

These are known as the citric acid cycle or Krebs cycle. It is a mystery whether this is something that life developed or if it was simply co-opted from something that did not need life to exist.
