Energy is conserved in endothermic reactions but is not conserved in exothermic reactions.
Endothermic reactions involve changes in the nucleus of an atom, but exothermic reactions do not involve changes in the nucleus.
Energy is absorbed in endothermic reactions but is released in exothermic reactions.
Endothermic reactions occur when electrons are shared between atoms, but exothermic reactions occur when electrons are transferred between atoms.
