The diagram below shows the energy conversions of the Krebs cycle, which is part of cellular respiration. The U-shaped arrows that show changes for NAD+, FAD, and ADP molecules represent energy conversions. From each glucose molecule, two acetyl-CoA molecules are made for the Krebs cycle.

Each acetyl-CoA through the Krebs cycle converts 3 NAD+ → NADH, 1 FAD → FADH2, and 1 ADP → ATP (3 + 1 + 1 = 5). For two acetyl‑CoA: 5 × 2 = 10 conversions.
