Apoptosis is an important cellular process where cells within an organism undergo controlled cell death. What is one example of how controlled cell death is used by organisms? Contrast apoptosis with necrosis. What is necrosis and why might an organism benefit from apoptosis instead of necrosis? One of the first steps in apoptosis often involves breaking down the mitochondrial membrane. Explain how this leads rapidly to cell death.
