Cellular metabolism self-adapts to protect against free radicals

Oxygen-consuming organisms obtain energy through cellular respiration, which is the transformation of carbohydrates and oxygen into carbon dioxide and water. This process also produces toxic oxygen radicals which must be decomposed immediately, as they would otherwise cause damage to cells. Scientists have now discovered a mechanism, with whose help cells can coordinate respiratory activity and the degradation of free radicals. Thus, the cells prepare their metabolism for free radicals before they even arise.
