What is the energy released in the fusion of four protons to form a helium nucleus ?

Energy is released in the process of

How is energy released in the cytoplasm

The binding energies per nucleon for deuteron (._1H^2) and helium (._2He^4) are 1.1 MeV and 7.0 MeV respectively. Calculate the energy released, when two deuterons fuse to form a helium nucleus.

The binding energy par nucleon for deuterium (""_(1)^(2)H) and helium (""_(4)^(2)He) are 1.1 MeV and 7.0 MeV respectively. The energy released when two deutrons fuse to form a helium nucleus (""_(4)^(2)He) is K(10^(7)) MeV, where K= ……… (nearly)
