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
An enzyme involved in the catabolism of fructose to pyruvate in the liver is 
Select and explain. 
A. Glyceraldehyde–3–phosphate dehydrogenase, B. Phosphoglucomutase, C. Lactate-dehydrogenase, D. Glucokinase
A: Glyceraldehyde–3–phosphate dehydrogenase
Answer: A: Glyceraldehyde–3–phosphate dehydrogenase 
Explanation: Glyceraldehyde-3-phosphate dehydrogenase 

Fructose is converted glyceroldehyde-3-phosphate which, in turn, is metabolised to pyruvate by glycolysis.
Amongst the given options, only glyceraldehyde-3-phosphate dehydrogenase is the enzyme which is involved in glycolysis after formation of glyceraldehyde-3-phosphate dehydrogenase.
