During ischemia-reperfusion injury in cardiac tissue, researchers observe two distinct phases of cell death. In the first phase, cells show ATP depletion, loss of membrane potential, and random DNA degradation. In the second phase, following reperfusion, some cells exhibit caspase activation, phosphatidylserine externalization, and ladder-pattern DNA fragmentation. What best explains this biphasic cell death pattern?
