How is the first step of the proton-proton chain different from that of the CNO cycle? The proton-proton chain begins with the fusion of two hydrogen nuclei to form deuterium, whereas the CNO cycle begins with a carbon nucleus decaying to produce a nucleus of nitrogen. The proton-proton chain begins with the fusion of two hydrogen nuclei to form deuterium, whereas the CNO cycle begins with a carbon nucleus capturing a hydrogen nucleus. The proton-proton chain begins with two deuterium nuclei fusing with a hydrogen nucleus, whereas the CNO cycle begins with a carbon nucleus fusing with a deuterium nucleus. The proton-proton chain begins with four hydrogen nuclei fusing to form a helium nucleus, whereas the CNO cycle begins with a carbon nucleus decaying to produce a nucleus of nitrogen.
Expert Answer
The proton-proton chain and the CNO cycle are both nuclear fusion processes that occur in the cores of stars, including our sun. They are the primary
