It is called tricarboxylic acid cycle because the citric acid is both the first product and the final reactant, and it contains three carboxyl groups.

A series of reactions in which the following transformations occur:

a 2 carbon compound enters the cycle and combines with a 4 carbon compound, and from this 6 carbon compound citric acid, 2 carbons are removed in separate stages as carbon dioxide (decarboxylation), eventually regenerating the 4 carbon compound so that the cycle can continue(pairs of) hydrogen atoms are removed by hydrogen acceptors NAD (x3) and FAD, which are then passed to the hydrogen and electron transport chain to make ATPATP is generated directly as a result of transfer of energy from molecules as they are converted from one form to another
