  sub:_4 prov:value "However, this detoxification process can be overwhelmed in some circumstances. One such circumstance is the depletion of mitochondrial, reduced glutathione. Normally, glutathione peroxidase plays a key role in H2O2 detoxification, as liver mitochondria do not have catalase. However, glutathione peroxidase needs adequate amounts of reduced glutathione in the mitochondrial matrix to detoxify H2O2. The depletion of mitochondrial glutathione below a critical threshold can impair mitochondrial H2O2 detoxification, which can trigger mitochondrial dysfunction, mitochondrial permeability transition (MPT) and cell death [22]." ;
