It arises from the internal energy of the nucleus, called the binding energy. In the case of light elements, joining two light nuclei to make a heavier one releases energy, because the binding energy changes. In the case of the heavy elements like uranium, splitting the nucleus into two smaller parts also releases energy, for the same reason. In both cases the end result loses a proportion of the initial mass of the nuclei concerned, and this loss of mass equates to the energy released via Einstein's equation E = mc2.
Change of H of fusion (∆Hfusion) is the enthalpy change going from solid to liquid or liquid to solid. That is, it is only for the phase change, and it is not accompanied by a change in temperature. It can be related to the ∆H of reaction but one would have to know the reaction to be more specific.
The energy for an endergonic reaction can come from an exergonic reaction, where energy is released. This released energy is then used to drive the endergonic reaction forward.
Fission is the opposite reaction to fusion. Fission involves the splitting of a heavy atomic nucleus into lighter elements, releasing a large amount of energy in the process.
nuclear fusion. This process releases large amounts of energy and is the primary source of power for the sun and other stars. It involves the merging of lighter atomic nuclei to form a heavier nucleus.
The fusion of deuterium (D) and hydrogen (H) involves the fusion of two deuterium nuclei to form a helium-3 nucleus and a neutron. The equation for this reaction is: 2D + 1H → 3He + n + energy.
From the nuclear fusion reaction in the sun
In a fusion reaction, the energy comes from the process of combining light atomic nuclei to form a heavier nucleus. This process releases a large amount of energy due to the conversion of mass into energy, as described by Einstein's famous equation Emc2.
Nuclear energy is either:fission reaction, orfusion reaction, orradioactive decay
In nuclear fusion reaction two nuclei are combined by providing the energy.

Fusion Reaction of Hydrogen
The easiest fusion reaction to make is between deuterium and tritium, two isotopes of hydrogen. This reaction requires the least amount of energy to initiate and is being pursued for fusion energy research.
