The biological process by which pyruvate is converted to Acetyl CoA, then to citrate, then isocitrate, alpha-ketoglutarate, succinyl CoA, succinate, fumarate, malate and then oxaloacetate (I can't believe I still remember all that!). The oxaloacetate then recieves 2 carbons from acetyl CoA to form citrate, and the cycle is repeated until we get tired and die. Oh yeah - some ATP is produced as well as NADH and FADH2. Comes after glycolysis and before the Electron Transport Chain in the process of respiration. Also called the citric acid cycle.
