In the CNO cycle, what specific function do carbon, nitrogen, and oxygen nuclei perform?

Answer

They act as catalysts, being temporarily consumed and then regenerated.

Carbon, nitrogen, and oxygen nuclei are utilized during the CNO cycle to facilitate the fusion of protons into helium, but they are regenerated by the end of the reaction sequence.
