The primary products of one complete turn of the Krebs cycle (citric acid cycle) are 3 molecules of NADH, 1 molecule of FADH₂, 1 molecule of GTP (or ATP depending on the cell type), 2 molecules of CO₂, and 1 molecule of Coenzyme A (CoA-SH). Since each glucose molecule generates two molecules of acetyl-CoA, the cycle turns twice per glucose molecule, doubling these products. These molecules are crucial for cellular energy metabolism. NADH and FADH₂ carry high-energy electrons to the electron transport chain for ATP synthesis, while CO₂ is a waste product expelled from the cell.
