How much $MeV$ energy is emitted by the fission of one nucleus of uranium-$235$ (in $MeV$)?

Nuclear fusion is common to the pair:

Nuclear fission is best explained by
[$AIPMT$ $2000$]

In an $\alpha -$ decay,the kinetic energy of the $\alpha -$ particle is $48 \ MeV$ and the $Q$ value of the reaction is $50 \ MeV$. The mass number of the mother nucleus is (assume that the daughter nucleus is in the ground state).

Which of the following are suitable for the fusion process?

Mention the use of controlled nuclear fission. Mention the use of uncontrolled nuclear fission.
