1-requires carbon
2-requires carbon for photosynthesis to occur
3-carbon is an output of cellular resp.

Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of
