key term - Programmed Cell Death

Definition

Programmed cell death, also known as apoptosis, is a tightly regulated process in which cells with damaged DNA or other abnormalities are intentionally eliminated to prevent harm to the organism. It involves controlled cellular self-destruction and removal without causing inflammation.

Related terms

Necrosis: Necrosis is an uncontrolled form of cell death that occurs due to injury or disease. Unlike apoptosis, necrosis leads to inflammation and can damage surrounding tissues.

Caspases: Caspases are enzymes that play a crucial role in initiating and executing programmed cell death by breaking down key cellular components.

Mitochondria:

Mitochondria are known as the powerhouses of the cell but also play an important role in regulating apoptosis by releasing certain molecules that trigger the process.
