The citric acid cycle, together with the electron transport system, constitutes stage III of catabolism (see Figure 8.2), also called cellular respiration. Because the citric acid cycle functions in both catabolism (Figure 11.1) and anabolism (Figure 11.2), we call it an amphibolic pathway. The citric acid cycle plays a pivotal role in cellular respiration, has multiple interconnections with other pathways, and provides for interconversions of numerous metabolites.
