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.
The majority of data relevant to the Krebs cycle findings were collected by Johnson, whereas Krebs provided the overall direction and intellectual stimulus for the research, according to an interview conducted with Johnson in 1993. [1] [2]
[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 ...

The citric acid cycle is also called the Krebs cycle or the tricarboxylic acid cycle. When oxygen is present, acetyl-CoA is produced from the pyruvate molecules created from glycolysis. Once acetyl-CoA is formed, aerobic or anaerobic respiration can occur. When oxygen is present, the mitochondria will undergo aerobic respiration which leads to ...
Fumarase deficiency (or fumaric aciduria) is an exceedingly rare autosomal recessive metabolic disorder in the Krebs cycle, characterized by a deficiency of the enzyme fumarate hydratase, which causes a buildup of fumaric acid in the urine and a deficiency of malate.

Spatial movements occur between mitochondria and cytosol and chemical transformations create various Krebs cycle intermediates. In all variants, pyruvate is imported into the mitochondrion for processing through part of the Krebs cycle. In addition to pyruvate, alpha-ketoglutarate may also be imported.
