The '''citric acid cycle''', also known as the '''TCA cycle''' (TCA = tricarboxylic citric acid) or the '''Krebs cycle''', is a series of chemical reactions that occur inside the cell that is part of the process of energy generation (both [[aerobic respiration]] and [[anaerobic respiration]]). In [[eukaryotic cell]]s, this cycle occurs inside the [[mitochondrion]], whereas in [[prokaryotic cell]]s, this cycle occurs directly within the [[cytoplasm]].
