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.

The researchers have demonstrated in the lab an enzyme-free metabolic pathway that mirrors the important Krebs cycle present in living organisms today. It is sparked by particles called sulphate ...
