    Study Notes

    Apoptosis: Programmed Cell Death

    • Apoptosis is a form of programmed cell death.
    • During apoptosis, cells activate enzymes that break down their own DNA and proteins.
    • This enzymatic degradation targets both nuclear and cytoplasmic components.
    • The cell fragments into smaller pieces after the breakdown.
    • The term "apoptosis," meaning "falling off," describes this fragmentation process.
