What vocabulary term describes the final stage of cellular life where no response occurs?

The term that describes the final stage of cellular life where no response occurs is cellular death. This stage follows the cessation of all biological functions that sustain life at the cellular level. During cellular death, cells become nonresponsive due to the depletion of energy and the failure of cellular processes.

It is critical to understand that this phase is distinct from somatic death, which refers to the complete and irreversible cessation of all functions of an organism as a whole. While cellular death can occur prior to somatic death, indicating a breakdown at the cellular level, somatic death reflects the death of the entire organism. The terminal stage refers to the final period in an illness before death, and the agonal phase signifies the transitional period just before death where physiological changes begin. Therefore, cellular death specifically identifies the point at which individual cells cease to function and become inactive.
