The fusion of elements in the cores of stars releases energy that supports the star against its own gravity, but this cycle ends with the fusion of iron. Iron fusion absorbs energy rather than releases it, so the core can no longer support itself, leading to a catastrophic collapse and a supernova explosion. This is why iron is considered the dead end for cores of massive stars.
