abstract:A futile cycle, also known as a substrate cycle, occurs when two metabolic pathways run simultaneously in opposite directions and have no overall effect other than to dissipate energy in the form of heat. For example, if glycolysis and gluconeogenesis were to be active at the same time, glucose would be converted to pyruvate by glycolysis and then converted back to glucose by gluconeogenesis, with an overall consumption of ATP.
Yet the progressive economic policy-making coming out of Washington today rests on the futile attempt to escape the corporate cycle of life that lies at the heart of capitalism.
