Study Notes

Apoptosis

Apoptosis is a process of programmed cell death.
Apoptosis is essential for maintaining tissue homeostasis and removing damaged or unnecessary cells.
Factors that can trigger apoptosis include:
- Free radicals: Highly reactive molecules that can damage cellular components.
- DNA damage: Alterations to the genetic material of a cell.
- Growth factor deprivation: The absence of signals that promote cell growth and survival.
- Lack of oxygen and nutrients: Conditions that can compromise cellular function and viability.
