[{'content': 'Amphibolic cycle is ? \nSelect and explain. \nA. Citric acid cycle, B. Glycolysis, C. Protein synthesis, D. Lipolysis', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Ans. is \'a\' i.e., Citric acid cycleMetabolic pathways fall into three categories :?Anabolic pathways:- Involved in synthesis of larger and more complex compounds from smaller precursors, e.g. synthesis of protein from amino acids, triglyceride synthesis, cholesterol synthesis, etc.Catabolic pathway:- Involved in the breakdown of larger molecules, commonly involving oxidative reaction. They are exothermic reactions producing reducing equivalents and mainly the ETC, ATP. Example are glycolysis, 13-oxidation of fatty acid etc.Amphibolic pathway:- occur at the "crossroads" of metabolism, acting as links between the anabolic and catabolic pathways, eg. the citric acid cycle.', 'role': 'assistant'}]
