Calculate the # of ATP produced from the complete oxidation of 1 glucose molecule during rest?
During rest an organism perform aerobic respiration in which the glucose molecules get oxidized to give ATP. In aerobic respiration a total of 36 ATP are produced from one molecule of glucose.
The Glycolysis produces 2 ATP and 2 NADH molecule. Each NADH again gets oxidized in the presence of Oxygen to give 3 ATP , hence a total of 8 ATP molecules are produced in Glycolysis.
In the Citric acid cycle, one molecule of acetyl co- A produces one molecule of ATP along with 3 NADH and two FADH2 molecule. As two acetyl co A enters the citric acid cycle, hence a total of 2 ATP, 6 NADH and 4 FADH2 molecule are produced in the citric acid cycle.
In the oxidative phosphorylation step of aerobic respiration all of the previously produced NADH and FADH2 are oxidized to form ATP. The 6 NADH can produce a total of 18 ATP and 4 FADH2 can give 8 ATP.
Hence as a total, in Glycolysis 8 (2+6), and in Citric acid cycle 28 (2+18+8) ATP are produced and by complete oxidation of one molecule of glucose, a total of 36 ATP are formed from one molecule of glucose by the process of aerobic respiration takes place during rest.
