Mitochondrial stress response. Different levels of quality control exist within mitochondria to detect and repair defects that affect mitochondrial performance before reaching the point of inescapable cell death: (Mito-UPR) adjusting protein folding capacity by mitochondrial chaperones and proteases, (Mitodynamics) allowing exchange of material and promoting functional complementation, and (Mitophagy) eliminating damaged mitochondria.
