For each acetyl CoA entering the citric acid cycle, 1 ATP (or GTP, depending on the cell type), 3 NADH, and 1 FADH2 are produced, along with 2 molecules of CO2. Since there are three acetyl CoA molecules entering the cycle, the products will be tripled: 3 ATP, 9 NADH, and 3 FADH2, along with 6 CO2. The CoA is regenerated and reused in the cycle, so it's not a net product.
