Select and explain. 
A. Glyceraldehyde 3-Phosphate, B. Glycerol-3-Phosphate, C. 3 CO2, D. 6NADPH
B: Glycerol-3-Phosphate
Answer: B: Glycerol-3-Phosphate 
Explanation: Three molecules of glucose-6-phosphate give rise to three molecules of CO 2 and three 5-carbon sugars. These are rearranged to regenerate two molecules of glucose-6-phosphate and one molecule of the glycolytic intermediate, glyceraldehyde-3-phosphate. Since two molecules of glyceraldehyde-3-phosphate can regenerate glucose-6-phosphate, the pathway can account for the complete oxidation of glucose.
