TCA

Escherichia coli
The name of this metabolic pathway is derived from the citric acid (a tricarboxylic acid, often called citrate, as the ionized form predominates at biological pH[6]) that is consumed and then regenerated by this sequence of reactions to complete the cycle. The cycle consumes acetate (in the form of acetyl-CoA) and water, reduces NAD+ to NADH, releasing carbon dioxide. The NADH generated by the citric acid cycle is fed into the oxidative phosphorylation (electron transport) pathway. The net result of these two closely linked pathways is the oxidation of nutrients to produce usable chemical energy in the form of ATP.

TCA Cycle

Pseudomonas aeruginosa
The citric acid cycle (also named tricarboxylic acid (TCA) cycle or the Krebs cycle), is a collection of 9 enzyme-catalyzed chemical reactions that occur in all living cells undergoing aerobic respiration. The citric acid cycle itself was officially identified in 1937 by Hans Adolf Krebs, who received the Nobel Prize for this discovery in 1953. In eukaryotes, the citric acid cycle occurs in the mitochondria. In prokaryotes, the TCA cycle occurs in the cytoplasm. The TCA cycle starts with acetyl-CoA, which is the “fuel” for the entire cycle. This important molecule comes from the breakdown of glycogen (a stored form of glucose), fats, and many amino acids. At beginning, acetyl-CoA first transfers its 2-carbon acetyl group to the 4-carbon acceptor compound called oxaloacetate to form the 6-carbon compound (citrate) for which the cycle is named. The resulting citrate will have numbers of chemical transformations, whereby it loses one carboxyl group (leading to the 5-carbon compound called alpha-ketoglutarate) and then a second carboxyl group (leading to the 4-carbon compound called succinate). Succinate molecule is further oxidized to fumarate, then malate and finally oxaloacetate. The regeneration of the 4-carbon oxaloacetate, allows the TCA cycle to continue. Oxidation step generates energy that is transferring energy-rich electrons for NAD+ to form NADH in TCA cycle. Each acetyl group will generate 3 NADH in TCA cycle.

TCA Cycle

Saccharomyces cerevisiae
Citric acid cycle (also known as tricarboxylic acid cycle (TCA) and Krebs cycle) contains series of reactions that involved enzyme catalyzation which are essential for all living cells that require oxygen for cellular respiration. In mitochondria (for eukaryotes), TCA cycle begins with acetyl-CoA and oxaloacetic acid (oxaloacetate) be catalyzed to form citric acid (citrate) by citrate synthase 3. Then, 3-isopropylmalate dehydratase with cofactor 4Fe-4S can catalyze citrate to form cis-aconitic acid as the intermediate compound and catalyze cis-aconitic acid to form isocitric acid. Many TCA cycle intermediates are the precursors for other molecules' synthesis; and NADH (from NAD+) is the major energy that is produced by oxidative steps of the TCA cycle.
