Under aerobic conditions, the TCA cycle, also known as the Krebs cycle or the citric acid cycle, occurs in the mitochondria and produces a sizable quantity of energy by providing electrons to three NADH and one FADH (flavin adenine dinucleotide),Pyruvic acid which then donates electrons to the electron transport chain and produces the proton gradient.
The byproduct of glycolysis created in the cell's cytoplasm is pyruvic acid. Pyruvic acid converts into acetyl Coenzyme A through a number of processes (acetyl CoA). Pyruvic acid is transformed into Acetyl CoA in the mitochondrial matrix. Acetyl CoA begins the citric acid cycle by being metabolized to oxaloacetate, an intermediate substance, and subsequently to citric acid, the cycle's first stable product.
