If you took biochemistry classes, chances are good you remember memorizing the Krebs cycle, a well-known metabolic pathway in which sugars are converted through a series of steps to generate ATP, a ...

The Krebs cycle may be like a busy roundabout, as vehicles whizz in and out from different junctions Transformer: The deep chemistry of life and death Nick Lane Profile Books IF WE want to ...

The Krebs cycle represents a common meeting place of carbohydrate, lipid, and protein metabolism. It variously serves as a means to produce energy, generate intermediates, and convert molecules ...

Two simple molecules can react to form most of the intermediates in an analog of the modern-day Krebs cycle, without the need for enzymes or metals, according to a new study (Nat. Chem. 2020, DOI ...

What would be the perfect revenge for a scientist whose paper is turned away from Nature? A Nobel Prize, of course. Such was the case for Hans Krebs, the biochemist who nabbed the award in 1953 for ...

Unfinished cycle However, the enzyme-free Krebs cycle that Ralser observed isn’t the complete biochemical cycle as it operates in modern cells. That may have come later, after enzymes evolved.
