Apoptosis occurs within extrinsic pathway and intrinsic pathways. Extrinsic pathway occurs by the simulation of a death receptor which is located on the plasma membrane. (Ligands are signal molecules that simulate death receptors.) Intrinsic pathway occurs by releasing of signals within mitochondria cells. (Cellular stress triggers intrinsic pathway. Cell stress is caused by DNA damage and heat shock.) [http://www.scq.ubc.ca/?p=350] | Apoptosis occurs within extrinsic pathway and intrinsic pathways.
