What does Krebs cycle produce?

The Krebs cycle produces several key molecules per turn: 3 NADH, 1 FADH₂, 1 GTP (or ATP), and 2 CO₂. It also regenerates oxaloacetate, the molecule required to initiate each new cycle turn. The NADH and FADH₂ produced carry high-energy electrons to the electron transport chain for ATP production. CO₂ is released as a metabolic waste product. The cycle also provides intermediate compounds for biosynthesis of amino acids, nucleotides, and other biomolecules.
