Understand that glucose is first converted into two molecules of pyruvate through glycolysis.
Each pyruvate molecule is then converted into acetyl-CoA, which enters the citric acid cycle.
Recognize that each acetyl-CoA molecule results in one turn of the citric acid cycle.
Since one glucose molecule produces two acetyl-CoA molecules, it will require two turns of the citric acid cycle to completely oxidize the products of one glucose molecule.
Therefore, the complete oxidation of one glucose molecule through the citric acid cycle requires two turns.
