← Life Sciences & MedicineWhich mechanism explains why damaged mitochondria trigger cellular self-destruction (apoptosis)?
A)Increased ATP production supports survival
B)Cytochrome c release activates caspases✓
C)Mitochondrial fusion repairs the damage
D)Enhanced glycolysis prevents cell death
💡 Explanation
Cytochrome c release from damaged mitochondria activates caspase enzymes, initiating apoptosis because this intrinsic pathway signals irreversible cellular damage, therefore the programmed cell death removes potentially harmful cells, rather than allowing them to survive with compromised function.
