    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.

  • Citric acid cycle - Wikipedia

    The citric acid cycle is a key metabolic pathway that connects carbohydrate, fat, and protein metabolism. The reactions of the cycle are carried out by eight enzymes that completely oxidize acetate (a two carbon molecule), in the form of acetyl-CoA, into two molecules each of carbon dioxide and water.

  • Electron Transport Chain (ETC): Definition, Location & Importance

    The citric acid cycle takes place in the matrix, and it produces some of the compounds used by the ETC. The ETC takes electrons from these compounds and returns the products back to the citric acid cycle. The folds of the inner membrane give it a large surface area with lots of room for electron transport chain reactions.

    The function of the citric acid cycle is the harvesting of high-energy electrons from carbon fuels. Note that the citric acid cycle itself neither generates a large amount of ATP nor includes oxygen as a reactant (Figure 17.3). Instead, the citric acid cycle removes electrons from acetyl CoA and uses these electrons to form NADH and FADH 2.
