During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2. ATP NAD+ NADH Citric acid is broken down into a 5-carbon compound, then into a 4-carbon com- pound. Along the way, two more molecules of CO2 are released, and electrons join NAD+ and FAD, forming NADH and FADH2.
