The mitochondria is a mediator of the cell apoptosis process, since it produces substances that allow programmed cell death, in the context of the intrinsic pathway of cell destruction.

Explanation:

Apoptosis is a form of cell regulation that involves the destruction of a cell or programmed cell death, where mitochondria play an important role in triggering the process.

The steps that occur in mitochondrial induction of apoptosis are:

In the space between the outer and inner membranes of the mitochondria there are proteins, cytochrome C (CitC). Bcl2 activating proteins promote the activation and release of Cit C The permeability of the mitochondrial membrane increases, allowing the exit of Cit C to the cytoplasm. CitC activates caspases, proteases involved in the process of degradation of cellular elements.

Necrosis - unlike apoptosis - occurs when an external agent causes inflammation and cell death.
