What are the final energetic products of each round of the Krebs cycle? Where is most part of the utile energy at the end of Krebs cycle found?
After each round of the Krebs cycle two carbon dioxide molecules, eight protons (hydrogen ions) captured by NAD and FAD (a hydrogen acceptor too) and one ATP molecule are formed.
During the Krebs cycle acetyl CoA is degraded. At the end the utile energy is incorporated into hydrogens transported by FADH2 and NADH2 molecules.
