[{'content': 'Which one of the following metabolites is used by all cells for glycolysis, glycogen synthesis, and the hexose monophosphate shunt pathway? \nSelect and explain. \nA. Glucose-1-phosphate, B. Glucose-6-phosphate, C. UDP-glucose, D. Fructose-6-phosphate', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Glucose-6-phosphate is common to all pathways. It can be converted to glucose-1-phosphate for glycogen synthesis or go directly into the pentose phosphate pathway or proceed through fructose-6-phosphate in glycolysis. UDP-glucose is formed from glucose-1-phosphate and can be used to form glycogen, lactose, glycoproteins, and glycolipids.', 'role': 'assistant'}]
