The Krebs cycle is named after its discoverer, ... The rest of the reactions in cellular respiration are aerobic, therefore requiring oxygen, and occur in the mitochondria of the cell.

The Krebs cycle may be like a busy roundabout, as vehicles whizz in and out from different junctions Transformer: ... paving the way for the modern Krebs, which requires oxygen.

Oxygen is so hungry for electrons—its outer shell needs only two more to get a complete set—that in effect it pulls them all the way through the Krebs cycle, which is the real powerhouse of ...

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.

Despite the anaerobic nature of the phosphagen system and glycolysis, oxygen is still present. These two anaerobic systems simply do not use oxygen to produce ATP, since that is a much slower process.

They have shown an enzyme-free metabolic pathway that mirrors the Krebs cycle. It is sparked by particles called sulphate radicals under conditions similar to those on Earth four billion years ago.

The Krebs cycle uses about two-thirds of the total oxygen consumed by the body, and generates about ⅔ of the energy. It plays a role in gluconeogenesis, transamination, deamination, and lipogenesis.
