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 … See more The citric acid cycle (CAC)—also known as the Krebs cycle or the TCA cycle (tricarboxylic acid cycle) —is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from See more Several of the components and reactions of the citric acid cycle were established in the 1930s by the research of Albert Szent-Györgyi, who received the Nobel Prize in Physiology or Medicine See more Products of the first turn of the cycle are one GTP (or ATP), three NADH, one FADH2 and two CO2. Because two acetyl … See more While the citric acid cycle is in general highly conserved, there is significant variability in the enzymes found in different taxa (note that the … See more There are ten basic steps in the citric acid cycle, as outlined below. The cycle is continuously supplied with new carbon in the form of acetyl-CoA, entering at step 0 in the table.
