  • Citric Acid Cycle or Krebs Cycle Overview - ThoughtCo

    Sir Krebs outlined the steps of the cycle in 1937. For this reason, it may be called the Krebs cycle. It's also known as the citric acid cycle, for the molecule that is consumed and then regenerated. Another name for citric acid is tricarboxylic acid, so the set of reactions is sometimes called the tricarboxylic acid cycle or TCA cycle.

    In the oxidation of pyruvate to acetyl CoA, one carbon atom is released as CO2. However, the oxidation of the remaining two carbon atoms—in acetate—to CO2 requires a complex, eight-step pathway—the citric acid cycle.

  • The Citric Acid (Krebs) Cycle | Boundless Microbiology

    The Citric Acid Cycle: The citric acid cycle, or Krebs cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidization of acetate—derived from carbohydrates, fats, and proteins—into carbon dioxide. In addition, the cycle provides precursors including certain amino acids as well as the ...

  • What Is the Purpose of the Krebs Cycle? | Reference.com

    The cycle is named after German-born British physician and biochemist Hans Adolf Krebs, who identified the citric acid cycle in the human body while working at the University of Sheffield in 1937. In recognition of the significance of this work, Krebs was awarded the Nobel Prize for Physiology or Medicine in 1953.

  • Learn About the 3 Main Stages of Cellular Respiration

    The Citric Acid Cycle, also known as the tricarboxylic acid cycle or the Krebs Cycle, begins after the two molecules of the three carbon sugar produced in glycolysis are converted to a slightly different compound (acetyl CoA).

  • The Citric Acid Cycle - Biochemistry - NCBI Bookshelf

    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.

  • Glyoxylate cycle - Wikipedia

    The two initial steps of the glyoxylate cycle are identical to those in the citric acid cycle: acetate → citrate → isocitrate. In the next step, catalyzed by the first glyoxylate cycle enzyme, isocitrate lyase, isocitrate undergoes cleavage into succinate and glyoxylate (the latter gives the cycle its name).

  • Glycolysis | Cellular respiration | Biology (article) | Khan ...

    Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.

  • Urea cycle - Wikipedia

    Link with the citric acid cycle. The urea cycle and the citric acid cycle are independent cycles but are linked. One of the nitrogens in the urea cycle is obtained from the transamination of oxaloacetate to aspartate. The fumarate that is produced in step three is also an intermediate in the citric acid cycle and is returned to that cycle.
