Abstract An organism’s survival depends on its ability to adapt to stress. Mitochondria are the cellular integrators of
environmental stressors that ultimately translate their responses at the organismal level, and are thus central to the
process whereby organisms adapt to their respective environments. Mitochondria produce molecular energy via
oxidative phosphorylation that then allows cells to biosynthetically respond and adapt to changes in their
environment. Reactive oxygen species (ROS) are by-products of oxidative phosphorylation that can be either
beneficial or damaging, depending on the context; ROS are hence both the conveyors of environmental stress as well
as cellular “adaptogens”. Mitohormesis refers to… More >
