Powerhouse of the cell has self-preservation mechanism

(Tokyo University of Agriculture and Technology) Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells. But when produced too abundantly, they damage DNA and render some cellular components dysfunctional. Now, an international research team has revealed how mitochondria keep their reactive oxygen species production in check.
