The overall result of the proton-proton chain is that ________
Delicious77 [7]

A gamma ray = energy.
The chain converts hydrogen into helium and makes energy.

This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.

Hope this helps!

This same natural selection also favors those genes that make it effective when the body that carries them is in development to extract all possible parental investment from their parents.
