What would happen if a cell's lysosomes burst? Quick Answer. If a cell's lysosomes burst, the enzymes released would severely damage various components of the cell, potentially killing it. Lysosomes are small, membrane-bound vesicles, or containers, which the cell fills with powerful digestive enzymes for use when needed to digest food items.
The appearance of extracellular virus signals the bursting or lysis of the infected cell, bringing the multiplication cycle to a conclusion. The total number of progeny virus per cell is known as the burst size. In lytic bacteriophage, the one step multiplication cycle takes from 10 to 45 minutes. The burst sizes of DNA phages are between 100 and 200 pfu/cell.
