Practice Question
Why does hypoxia lead to cell membrane rupture?
Answer Choices:
Correct Answer:
Sodium accumulates inside the cell due to ATP depletion.
Rationale:
🟢 Hypoxia reduces ATP production, which is essential for the sodium-potassium pump.
🟢 Without ATP, sodium accumulates inside the cell, pulling water in by osmosis.
🟢 The resulting cellular swelling stretches and weakens the cell membrane.
🟢 Eventually, the swollen cell undergoes membrane rupture, releasing contents.
🟢 This process explains why hypoxia is a leading cause of irreversible cell injury.
