Cellular adaptation is the ability of cells to respond to various types of stimuli and adverse environmental changes. CHAPTER 1 Cellular Adaptations, Cell Injury, and Cell Death 5 If the limits of adaptive response to a stimulus are exceeded, or in certain instances when the cell is exposed to an injuri-ous agent or stress, a sequence of events follows that is loosely termed cell injury.Cell injury is reversible up to a 1. … The proteins of the nucleus are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
