Because during the TCA Cycle (aka Kreb’s Cycle), energy is both consumed and produced. During the TCA cycle, acetyl coA is converted to CO2 and H2O but. The citric acid cycle is the central metabolic hub of the cell. It is the final common pathway for the oxidation of fuel molecule such as amino acids. Amphibolic Nature Of TCA Cycle: In aerobic organisms, the citric acid cycle is an amphibolic pathway, one that serves in both catabolic and anabolic processes.
