Why energy is released in a nuclear fission reaction?

In has been estimated that the total energy radiated by the sun is 3.8xx10^26 J per second. The source of energy of stars is a thermonuclear reaction called nuclear fusion. Fusion reactions are not controlled. It is presumed that the energy of stars is due to two processes called proton-proton cycle and carbon nitrogen cycle. Fusion cannot take place at ordinary temperature. This, hydrogen bomb uses a small fission bomb, which on explosion causes the temperature to rise very high about 10^7 K. We have yet to see how a hydrogen bomb can be used for peaceful life-sustaining purpose. Energy released in the process of fusion is due to mass defect. It is also called Q-value. Q =Deltamc^2 , Deltam= mass defect Answer the following questions based on above passage: Fusion reaction takes place at about:
