Mitochondria are double membrane-bound organelles found in most eukaryotic cells, and are also called as the “power houses” of the cells. The cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy are mostly produced by the mitochondria. In a study published in the EMBO Journal by Dr. João Passos at Newcastle University, it was established that the elimination of mitochondria from the cells resulted in the ageing cells to become more similar to the younger cells. This implies that the mitochondria are major triggers of cell ageing.
