Osmosis', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Ref. Guyton. 13th edition. Page. 840\nPrimary and secondary transport \n\nIn primary active transport, ATP is consumed directly by the transporting protein, (e.g., the Na/K-ATPase pump, or the calcium-dependent ATPase of the sarcoplasmic reticulum). \u2028\nSecondary active transport depends indirectly on ATP as a source of energy, as in the co-transport of Na-glucose in the proximal tubule. This process depends on ATP utilized by the Na/K-ATPase pump. \u2028\nGlucose moves up a concentration gradient via secondary active transport.', 'role': 'assistant'}]
