traumatic damage to cells

2

why does necrosis spread?

release of degradative enzymes from lysosomes

3

apoptosis is precise and repeatable deletion of cells

4

how are apoptotic cells removed?

by phagocytes

5

how do cells signal for apoptosis?

the lipid phosphatidylserine usually faces towards th inner monolayer, but it apoptotic cells it flips outwards

6

what happens to the chromatin in apoptotic cells?

it condenses

7

what enzymes are responsible for the dismantling of proteins in the cell during apoptosis?

caspases

8

what are viruses?

autonomous complexes of nucleic acids, which replicate inside the cell using its machinery

9

why might apoptosis occur in prokaryotes?

when conditions are poor, apoptosis might help provide nutrients for the other cells to use
