| oxidative stress |
Accumulation of destructive molecules called free radicals can lead to motor neuron death. Free radicals damage components of the cells' membranes, proteins or genetic material by "oxidizing" them-the same chemical reaction that causes iron to rust. Some patients with familial ALS have mutations in the gene for superoxide dismutase type 1 (SOD1). SOD1 normally breaks down free radicals, but mutant SOD1 is unable to perform this function. ...

| oxidative stress |
A state characterized by an excess of free radical groups in the body, which creates a potentially unstable cellular environment linked to tissue damage, accelerated aging, and degenerative disease. Oxidative stress can result from many factors, including exposure to alcohol, medications, poor nutrition, trauma, cold, toxins, and over-exercise.

| oxidative p. |
the formation of high energy phosphate bonds by phosphorylation of ADP to ATP coupled to the transfer of electrons from reduced coenzymes (NADH or FADH2) to molecular oxygen via the electron transport chain (see illustration at chain ). Three molecules of ATP per NADH and two per FADH2 are produced as a result of a proton gradient created across the mitochondrial inner membrane by the electron transport chain.
