What is Apoptosis of Cells

What is Apoptosis?

Apoptosis is defined as programmed cell death, which occurs very systematically.

Normally cell death can occur in two ways. One is by this apoptosis and the other is by necrosis, which occurs under pathogenic conditions or deficiencies.

Apoptosis is a highly ordered process. During apoptosis the cells are disassembled very systematically. They detach from the neighboring cells of the tissue and its protoplasm condenses. The membrane-bound organelles such as mitochondria disintegrate by releasing its contents into the cytoplasm. The enzymes, endonucleases, act on the chromatin materials and break the DNA into fragments. At the final stage the cell membrane starts forming blebs and the cell fragments into apoptosis bodies.

This type of cell death is a process of normal physiology and always occurs during organ development. Compared to apoptosis necrosis occurs in a disordered manner and occurs due to the action of toxins produced by the pathogens on the cell.
