Once cells stop receiving nutrients and oxygen via blood circulation jail cell start up anaerobiotic ventilation ( without oxygen ) by break adenosine tri - phosphate ( ATP ) into adenosine di - phosphate ( ADP ) to find vitality . Anerobic external respiration lasts for few hours , until all ATP backlog are exhausted . The anerobic respiration induce aggregation of lactic dose in cell tissues that disrupts cellular phone function . enzyme then collapse the cells and breaks them down.3
