Citric acid cycle or tricarboxylic acid (TCA) cycle is the part of cellular respiration. This cycle is carried out in the mitochondria matrix. Citric acid cycle begins with the entry of 2 carbon compound acetyl Coenzyme A (CoA). In one turn of the cycle, one molecule of acetyl CoA enters into the cycle. On completion of one turn of  citric acid cycle, two molecules of carbon dioxide, 3 molecules of reduced NADH and one molecule of reduced FADH₂ and 1 molecule of GTP are produced.
