Phagocytosis', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Apoptosis results from the activation of enzymes called caspases (so named because they are cysteine proteases that cleave proteins after aspaic residues). The activation of caspases depends on a finely tuned balance between production of pro- and anti-apoptotic proteins. Two distinct pathways converge on caspase activation: the mitochondrial pathway and the death receptor pathway.( Robbins Basic Pathology, 9th edition, page 19 )', 'role': 'assistant'}]
