Why do cancer cells typically consume more glucose?
Because of the upregulation of non-aerobic glycolysis, cancer cells move glucose through the glycolytic pathway, making lactate and reusing NADH. This is due to relative hypoxia producing a deficiency of oxygen that is needed to run the TCA cycle. This shift from oxidative phosphorylation to glycolysis is known as the Warburg effect.
