The net production of ATP through the complete citric acid cycle also known as the Krebs cycle or TCA cycle and oxidative phosphorylation can be calculated by considering the different stages of cellular respiration. Cellular respiration consists of glycolysis, the citric acid cycle, and oxidative phosphorylation.1. Glycolysis: In glycolysis, one glucose molecule is converted into two pyruvate molecules, generating a net gain of 2 ATP molecules and 2 NADH molecules.2. Pyruvate Decarboxylation: Each pyruvate molecule is converted into an Acetyl-CoA molecule, producing 1 NADH molecule per pyruvate. Since there are two pyruvate molecules, a total of 2 NADH molecules are produced in this step.3. Citric Acid Cycle: For each Acetyl-CoA molecule entering the cycle, 1 ATP, 3 NADH, and 1 FADH2 molecule are produced. Since there are two Acetyl-CoA molecules one from each pyruvate , the cycle generates a total of 2 ATP, 6 NADH, and 2 FADH2 molecules.4. Oxidative Phosphorylation: In the electron transport chain, NADH and FADH2 molecules are used to generate ATP. Each NADH molecule generates approximately 2.5 ATP molecules, while each FADH2 molecule generates approximately 1.5 ATP molecules.Now, let's calculate the total ATP production:- Glycolysis: 2 ATP- Citric Acid Cycle: 2 ATP- Oxidative Phosphorylation: 10 NADH 2.5 ATP/NADH + 2 FADH2 1.5 ATP/FADH2 = 25 ATP + 3 ATP = 28 ATPThe net production of ATP through the complete citric acid cycle and oxidative phosphorylation is approximately 32 ATP molecules per glucose molecule. However, it is important to note that the actual ATP yield may vary slightly depending on the efficiency of the electron transport chain and other cellular factors.
