Apoptosis

A process where cells naturally die and are broken down, essential for healthy function.

Mitochondria

Organelles responsible for energy production within cells, also involved in programmed cell death.

Cytochrome C

A protein released by mitochondria that signals the start of apoptosis.

Study Notes

Apoptosis: Cell Death

Apoptosis is a crucial biological process for eliminating aged or damaged cells.
Mitochondria are involved in initiating apoptosis.
Mitochondria release cytochrome C.
Cytochrome C activates caspase, a key enzyme in cell destruction during apoptosis.
Dysfunctional apoptosis is linked to diseases like cancer.
Mitochondria are thus thought to play a role in cancer development.
