Cover Story: Gear shifting is best known from car driving. On a flat highway, the highest gear gives the highest speed. When driving uphill, shifting to a lower gear may increase the speed and prevent stalling; the optimal gear number decreases with the increasing slope of the hill. Can living organisms shift gears? The answer is yes. Cells can engage in alternative pathways that enable them to continue making energy molecules (‘ATP’) when these contain more Gibbs energy, even though this uses more nutrient energy per energy molecule. The continued synthesis of the energy molecules enables the cells to utilize these for growth and survival when faced with thermodynamic challenges. View this paper
