(c) Lysis of the cell
Work Step by Step
Apoptosis is always triggered via a cell-signaling pathways. Both internal and external signals may begin a signal transduction pathway, activating such proteins as Ced-3 and Ced-4 which then activate other proteins that destroy the cell. Thus, answer option "(b) Cell-signaling pathways" is eliminated. Referenced on page 228, "cellular agents chop up the DNA" and during blebbing, the cellular contents are packaged into vesicles which are "digested by specialized scavenger cells," eliminating answer options "(a) Fragmentation of the DNA" and "(d) Digestion of cellular contents by scavenger cells." This leaves answer option "(c) Lysis of the cell." Cell lysis refers to the bursting open of a cell to release its contents, which is not what occurs during blebbing, the shrinking of the cell and splitting off of vesicles.
