Apoptosis, or programmed cell death, is a naturally occurring process in the body. It involves a controlled sequence of steps in which cells signal self termination. Apoptosis works to keep the body's natural cell division process of mitosis in check.
Apoptosis is programmed cell death or cell suicide. It is mainly initiated by the cutting off a portion of the inactive procaspases to make active caspases, which are proteins that speed up chemical reactions that start degrading parts of the cell and are the most important activator of cellular destruction.
