TCA Cycle (Citric acid cycle or Krebs cycle)

Krebs cycle

The tricarboxylic acid cycle (TCA cycle), also known as the citric acid cycle or the Krebs cycle, is a major energy-producing pathway in living bodies. Cells obtain ATP from breakdown of glucose in the absence of oxygen as in glycolysis. However, most organisms normally are aerobic and oxidize their organic fuels completely to CO2 and water. Foodstuffs feed into the citric acid cycle as acetyl-CoA and the acetyl-CoA is oxidized to carbon dioxide and water in order to generate energy. … Read more
