One turn of the citric acid cycle with the input of one acetyl-CoA molecule produces:1. 3 NADH molecules from the oxidation of isocitrate, -ketoglutarate, and malate 2. 1 FADH2 molecule from the oxidation of succinate 3. 1 GTP molecule from the conversion of succinyl-CoA to succinate During oxidative phosphorylation, NADH and FADH2 molecules are used to generate ATP through the electron transport chain and chemiosmosis. The number of ATP molecules produced per NADH and FADH2 varies depending on the organism and specific conditions, but a commonly used estimate is:1. 2.5 ATP molecules per NADH2. 1.5 ATP molecules per FADH2Using these estimates, the ATP production from one turn of the citric acid cycle and oxidative phosphorylation can be calculated as follows: 3 NADH 2.5 ATP/NADH + 1 FADH2 1.5 ATP/FADH2 + 1 GTP= 7.5 ATP + 1.5 ATP + 1 ATP= 10 ATP moleculesSo, approximately 10 ATP molecules are produced by one turn of the citric acid cycle and oxidative phosphorylation, given the input of one acetyl-CoA molecule into the cycle.
