Biochemistry. A series of oxidative reactions of central importance in all living cells that use oxygen as part of cellular respiration. The citric acid cycle comprises eight steps in which acetyl units derived from glucose, fatty acids or amino acids are metabolized to carbon dioxide, water, and energy in the form of phosphate bonds. In eukaryotes, the citric acid cycle occurs in the mitochondrial matrix.
