Overview of the citric acid cycle. The citric acid cycle—also known as the Krebs cycle, Szent–Györgyi–Krebs cycle, or TCA cycle (tricarboxylic acid cycle) [1] [2] —is a series of biochemical reactions to release the energy stored in nutrients through the oxidation of acetyl-CoA derived from carbohydrates, fats, proteins, and alcohol.
[32] [33] It is also known as the "Krebs cycle" or "tricarboxylic acid (TCA) cycle". Krebs sent a short manuscript account of the discovery to Nature on 10 June 1937. On 14 June, he received a rejection letter from the editor, saying that the journal had "already sufficient letters to fill correspondence columns for seven or eight weeks", and ...
John Krebs is the son of Sir Hans Adolf Krebs, the German biochemist who described the uptake and release of energy in cells (the Krebs cycle). [6] He was educated at the City of Oxford High School, and Pembroke College, Oxford, where he obtained a BA degree in 1966, upgraded to an MA degree in 1970, and received a DPhil degree in 1970.
Ketone bodies are water-soluble molecules or compounds that contain the ketone groups produced from fatty acids by the liver (ketogenesis). [1] [2] Ketone bodies are readily transported into tissues outside the liver, where they are converted into acetyl-CoA (acetyl-Coenzyme A) – which then enters the citric acid cycle (Krebs cycle) and is oxidized for energy.
The Reductive/Reverse TCA Cycle (rTCA cycle). Shown are all of the reactants, intermediates and products for this cycle. The reverse Krebs cycle (also known as the reverse tricarboxylic acid cycle, the reverse TCA cycle, or the reverse citric acid cycle, or the reductive tricarboxylic acid cycle, or the reductive TCA cycle) is a sequence of chemical reactions that are used by some bacteria and ...

The first phase of respiration is glycolysis, a series of ten biochemical reactions in the cytoplasm that convert glucose into pyruvate. Pyruvate is then transported into mitochondria, where it is converted by the pyruvate dehydrogenase complex into acetyl-CoA, the starting substrate of the Krebs cycle.
Phosphagen system (ATP-PCr) and purine nucleotide cycle (PNC) [1] The Purine Nucleotide Cycle is a metabolic pathway in protein metabolism requiring the amino acids aspartate and glutamate. The cycle is used to regulate the levels of adenine nucleotides, in which ammonia and fumarate are generated. [2] AMP converts into IMP and the byproduct ...
