The CNO cycle (carbon nitrogen oxygen) alternately called Bethe-Weizsäcker-cycle, is one of two types of fusion reactions by which stars convert hydrogen to helium, the other is the proton proton chain.
This is a series of nuclear fusion reactions that converts ordinary hydrogen (single protons) into helium in the cores of stars somewhat heavier than the sun. The carbon, nitrogen and oxygen are only catalysts; they are not formed or destroyed. See the Wikipedia article "CNO cycle" for all the gory details.
The most stable resonance structure for the CNO ion with nitrogen as the central atom is one where the negative charge is on the oxygen atom, and the double bond is between the carbon and nitrogen atoms.
The best Lewis structure for the fulminate ion (CNO-) has a formal charge of -1 on the central nitrogen atom. This is achieved by placing all three atoms in a linear structure with a triple bond between carbon and nitrogen, and a single bond between nitrogen and oxygen.
Citric Acid Cycle TCA Cycle (tricarboxcylic acid cycle).
The cycle that depends on water existing as a solid, liquid, and gas on Earth is the water cycle. This cycle involves processes like evaporation, condensation, and precipitation, which are facilitated by water's ability to exist in these different states.
The CNO cycle uses carbon, nitrogen, and oxygen as catalysts to convert hydrogen into helium, while the proton-proton chain fuses hydrogen into helium directly. The CNO cycle is more efficient in high-mass stars while the proton-proton chain dominates in lower-mass stars like the Sun.
Stars that produce most of their energy by the CNO cycle are predominantly those with a mass about 1.3 times the mass of our Sun or greater.Our Sun, and stars comparable in mass or less, predominantly use the proton-proton cycle.
It affects the internal structure of main-sequence stars because they have very high central temperatures for the extreme temperature sensitivity of the CNO cycle to fuse hydrogen into helium.
The Chief of Naval Operations, or CNO, is the highest ranking officer in the US Navy. The current CNO is ADM Gary Roughead.
The advisor to the Chief of Naval Operations (CNO) is the Vice Chief of Naval Operations (VCNO). The VCNO assists the CNO in his duties and responsibilities, particularly in matters pertaining to the operation and readiness of the U.S. Navy.

I can't remember if it is the proton-proton chain or if it's the CNO cycle... i'm pretty sure it's the CNO cycle, but i'm not 100% sure.

The Chief of Naval Operations (CNO) is typically based at the Pentagon in Arlington, Virginia, where the U.S. Navy's headquarters is located. While the CNO may have an official residence or accommodations in the area, they often travel frequently and may not have a fixed personal residence due to the demands of the position. Additionally, the CNO may spend time at various naval installations and facilities across the country and internationally.
The most important fusion process in nature is that which powers the stars. The net result is the fusion of four protons into one alpha particle, with the release of two positrons, two neutrinos (which changes two of the protons into neutrons), and energy, but several individual reactions are involved, depending on the mass of the star. For stars the size of the sun or smaller, the proton-proton chain dominates. In heavier stars, the CNO cycle is more important. Look up CNO cycle in Wikipedia
