Document Summary

Choosing a model: because they have e a fixed number of cells, the same cells die every time, they identified genes that lead to the death of these cell. It has to shed 131 cells every time and its always the same cells that die harmful for the neighbouring cells. Cell death: necrosis vs apoptosis: necrosis, swell until undergoes lysis, then rupture. Its taking in ions, water and the membrane is permeable. Which leads to the cell to tae ions (ca), its concentration ill stat to rise therefore acting as a stress. The er is releasing the ca stored in there, making it worse, because the ca is increasing, one enzymes called (calpain) becomes active wen there is a lot of ca, it goes to the lysosome. It will destroy the lysosome membrane, there are enzymes there *digestive enzymes) destroy.
