At its core, the TCA cycle is a series of chemical reactions that take place in the mitochondria, the powerhouses of the cell. These reactions convert carbohydrates, fats, and proteins into energy in the form of ATP (adenosine triphosphate). The TCA cycle begins with the breakdown of acetyl-CoA, a molecule produced from the digestion of food, into citrate. The cycle then proceeds through a series of reactions, ultimately producing NADH and FADH2, which are used to generate energy.
