The overall process of carbon nitrogen fusion cycle results in the fission of `4` protons to yield helium nucleus and_____

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

Energy is released from stars due to nuclear fusion taking place in two cycles proton-proton cycle and carbon nitrogen cycle. In these cycles four hydrogen nuclei combine to from helium nucleus. In this fusion reaction in addition to energy how many number of nutrinous are released ?

The sun is believed to be getting its energy form the fusion of four protons to form a helium nucleus and a pair of positrons. Calculate the release of energy per fusion in MeV. Mass of proton=1.007825 a.m.u. , mass of positron =0.000549 a.m.u., mass of helium nucleus =4.002603 a.m.u. Take 1a.m.u. =931MeV.

The nucleus finally formed in fusion of protons in proton-proton cycle is that of
