    Citric acid cycle - Wikipedia

    The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle, is a series of chemical reactions in the cell that breaks down food molecules into carbon dioxide, water, and energy.In plants and animals (eukaryotes), these reactions take place in the matrix of the mitochondria of the cell as part of cellular respiration. Many bacteria perform the citric acid cycle too .

    Citric Acid Cycle Summary. The initiating step of the citric acid cycle occurs when a four carbon compound (oxaloacetic acid) condenses with acetyl CoA (2 carbons) to form citric acid (6 carbons). The source of acetyl CoA is glycolysis or the fatty acid spiral. As the cycle proceeds, 2 carbons are converted into two CO 2 molecules at steps 5 and 6.
