This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Biochemistry
Which of the following is not a product of the glycolytic pathway? 
Select and explain. 
A. Fructose 2,6 biphosphate, B. Fructose 1,6 biphosphate, C. Glyceraldehyde-3-phosphate, D. None of the above
D: None of the above
Answer: D: None of the above 
Explanation: Please study the glycolytic pathway thoroughly. All the above are seen in it. Glycolysis is a definite sequence of ten reactions involving ten intermediate compounds. Fructose 2,6 biphosphate, Fructose 1,6 biphosphate, Glyceraldehyde -3- phosphate are intermediate products during the formation of pyruvate. The free energy released in this process is used to form the high-energy compounds ATP (adenosine triphosphate) and NADH (reduced nicotinamide adenine dinucleotide).
