Can cell damage be reversed

Answered By: Landon Carter Date: created: Apr 22 2021

Cell damage can be reversible or irreversible. Depending on the extent of injury, the cellular response may be adaptive and where possible, homeostasis is restored. Cell death occurs when the severity of the injury exceeds the cell’s ability to repair itself.
