All of the following statements are true regarding reversible cell injury Except
**Reversible Cell Injury**
**Core Concept**
Reversible cell injury, also known as hydropic change, is a type of cellular damage that occurs due to an imbalance between the cell's energy supply and demand. This condition is characterized by an accumulation of water and ions within the cell, leading to cellular swelling and disruption of normal cellular functions.
**Why the Correct Answer is Right**
The correct answer is related to the underlying pathophysiology of reversible cell injury. In this condition, the cell's mitochondria undergo a process called mitochondrial swelling, which disrupts the normal functioning of the electron transport chain and ATP production. This results in an accumulation of calcium ions within the cell, further exacerbating cellular damage. The cell's ability to maintain normal ion and water balance is compromised, leading to cellular swelling and eventual cell death if not reversed.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not accurately describe a characteristic of reversible cell injury.
* **Option B:** This option is incorrect because it is a feature of irreversible cell injury, not reversible cell injury.
* **Option D:** This option is incorrect because it is a consequence of irreversible cell injury, not reversible cell injury.
**Clinical Pearl / High-Yield Fact**
In the context of reversible cell injury, the cell's ability to maintain normal ion and water balance is crucial. The disruption of this balance leads to cellular swelling and eventual cell death. This highlights the importance of early intervention in treating conditions that cause reversible cell injury.
**Correct Answer: B. Irreversible cell injury is characterized by loss of plasma membrane integrity.**
