Final answer:
The intrinsic and extrinsic pathways of apoptosis both involve signaling cascades that lead to cell death, activating caspases that digest cellular proteins. The common events in both pathways include the activation of caspases, which are proteolytic enzymes that digest cellular proteins during the process of apoptosis.
Step-by-step explanation:
Apoptosis is a mechanism that allows cells to die in a controlled manner to prevent the release of potentially damaging molecules. Both the intrinsic and extrinsic pathways of apoptosis involve signaling cascades that lead to cell death. The common events in both pathways include the activation of caspases, which are proteolytic enzymes that digest cellular proteins during the process of apoptosis.
