[{'content': 'Common to both glycolysis and pentose phosphate pathway is: \nSelect and explain. \nA. Glucose 6 phosphate, B. NAD, C. ATP, D. All of the above', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Although glucose 6-phosphate is common to both pathways, the pentose phosphate pathway is markedly different from glycolysis. Oxidation utilizes NADP rather than NAD, and CO2, which is not produced in glycolysis, is a characteristic product. No ATP is generated in the pentose phosphate pathway, whereas it is a major product of glycolysis Ref: Harper 28th edition, chapter 21.', 'role': 'assistant'}]
