The article discusses the significance of tricarboxcylic acid (TCA) cell cycle to generate energy through adenosine triphosphate (ATP). It states that the ATP is generated through lipid and glucose breakdown which are important for the metabolic conditions since glycolysis is not enough to supply long-term needs of energy. It adds that fine-tuning of glycolysis can be vital to achieve energy needs of cells and to support organ function such as cardiac and lung tissue.
