The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle) is a series of chemical reactions of central importance in all living cells that use oxygen as part of cellular respiration. In aerobic organisms, the citric acid cycle is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. It is the second of three metabolic pathways that are involved in fuel molecule catabolism and ATP production, the other two being glycolysis and oxidative phosphorylation.
The citric acid cycle also provides precursors for many compounds such as certain amino acids, and some of its reactions are therefore important even in cells performing fermentation.

The Krebs Cycle is on of the 3 main phases of cellular respiration - Glycolisis, Kreb's Cycle, and Electron Transport Chain. This is an 8 step cycle to produce 2 ATP, 3 co2, 6 NADH, and 2 FADH2 from acetyl CoA (an ensyme in the body). It is aerobic (requires oxergen) and occurs in the mitochndria.

It's a complex cylce that (simply put) uses oxygen to form ATP (adenosine triphosphate) from AMP and ADP (energy) and then releases water and CO2 in the process.

Another name for it is the citric acid cycle, so be on the look out for that.
