Question

Quizplus · Accepted Answer

The CNO cycle (Carbon-Nitrogen-Oxygen cycle) is a set of nuclear fusion processes by which four hydrogen nuclei (protons) are combined into one helium nucleus, with carbon, nitrogen, and oxygen acting as catalysts in the process. This cycle plays a crucial role in stars more massive than the Sun.
