The statement “Earlier, chemists called the substrate cycle a futile cycle, which has now become a misnomer” is to be explained. Concept introduction: Substrate cycle: Two opposite reactions take place with different enzymes, along with different reaction pathways and conditions. For example, breakdown and formation of a molecule, phosphorylation and dephosphorylation, hydration and dehydration, and so on.
