Select and explain. 
A. Fructose-6-phosphate to glucose-6-Phosphate, B. Pyruvate to Lactate, C. Oxaloacetate to pyruvate, D. Pyruvate to Acetyl CoA
A: Fructose-6-phosphate to glucose-6-Phosphate
Answer: A: Fructose-6-phosphate to glucose-6-Phosphate 
Explanation: Glucose-6-phosphate to Fructose-6-phosphate occurs in Glycolysis But opposite of this i.e. Fructose 6 phosphate to Glucose 6 phosphate occurs in Gluconeogenesis.
