All cells need energy, which they get through ATP, an inherently unstable molecule that must continually be produced.  Though ATP can be produced in different ways, nearly all living cells can harness ATP through glycolysis, the stepwise degradation of glucose, and other sugars, obtained from the breakdown of carbohydrates without the need for molecular oxygen (anaerobic).  Glycolysis is an ancient, universal pathway that probably developed before there was sufficient oxygen in the atmosphere to sustain more effective methods of energy extraction.
