From each pyruvate molecule inserted, 3 Carbon Dioxide, 1 FADH2, 3 NADH and ATP molecule are produced.
Malic acid is used as a catalyst for this because it consumes pyruvic acid without building up lactic acid.  It consists of a series of 8 reactions, and, in the first, carbon atoms enter as acetyl-CoA, and the last reaction results in the regeneration of oxaloacetate. This cycle is both catabolic and anabolic. From each pyruvate molecule inserted, 3 Carbon Dioxide, 1 FADH2, 3 NADH and ATP molecule are produced. FTP, name this cycle that occurs in the mitochondria and uses oxygen in cellular respiration, also known as the Citric Acid Cycle.
