Citric acid cycle


Citric acid cycle is also known as tricarboxylic acid cycle (TCA cycle) and the Krebs cycle. it is a series of enzyme-catalysed chemical reactions, which have central importance in all living cells that use oxygen as part of cellular respiration.
In eukaryotic cells, the citric acid cycle occurs in the matrix of the mitochondrion,
In aerobic organisms, It is part of a metabolic pathway involved in the chemicaly conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy ATP and NADH. Befor this reaction Glycolysis And Pyruvate Oxidation Both reactions take place And after it Oxidative phosphorylation take place
