Question Detail
Question
Apoptosis can be triggered by which mitochondrial event?
Correct Answer
Option A is the correct answer.
Detailed Explanation
In the intrinsic pathway of apoptosis, cellular stress signals cause the mitochondrial outer membrane to become permeable, releasing cytochrome c into the cytoplasm. Cytochrome c then initiates the caspase cascade, leading to programmed cell death.
Hint
A key protein escapes from the mitochondria to signal death.
