The Citric Acid Cycle is a metabolic pathway that uses a two-carbon molecule, and a four-carbon molecule to form a six-carbon molecule that is used to produce NADH, carbon dioxide, ATP and FADH2. The cycle involves eight chemical reactions, and at the end, the original four-carbon molecule is produced. This animation takes a closer look at the substrates, reactions, and products involved in the pathway.
