Expert Solution
Step 1

One molecule of glucose gives two molecule of pyruvate, which enters TCA cycle for complete oxidation.

1,3-bisphosphoglycerate is an intermediate of glycolysis.

1,3-bisphosphoglycerate is converted to one molecule of pyruvate. This pyruvate enters TCA cycle for further complete oxidation.
