Which of the following is characterized by irreversible injury to cells? A) Normal plasma membrane integrity B) Stable lysosomal function C) Mitochondrial swelling D) Decreased intracellular calcium levels
Understand the Problem
The question is asking which option represents a characteristic of irreversible injury to cells. We are looking for a specific change or sign that indicates permanent damage is done to the cells.
Answer
Mitochondrial swelling
The final answer is Mitochondrial swelling.
Answer for screen readers
The final answer is Mitochondrial swelling.
More Information
Irreversible injury to cells is often associated with mitochondria-related changes such as mitochondrial swelling, formation of amorphous densities in mitochondria, and increased mitochondrial permeability.
Tips
A common mistake is to confuse reversible and irreversible cell injury characteristics. Other options listed may be involved in reversible injury but are not definitive indicators of irreversible damage.
