Na+ Ca2+ exchanger', 'role': 'user'}, {'content': 'Answer: D \nExplanation: ATP-dependent transpoers, as their name implies, use the energy in ATP to drive the movement of molecules/ ions across the membrane. There are two groups of ATP-dependent transpoers: ATPase ion transpoers and ATP-binding cassette (ABC) transpoers.Na+ K+ ATPase , H+ ATPase , CFTR is an example for ATP-binding cassette (ABC) transpoer. Na+ Ca2+ exchanger is a secondary active transpoer.Reference: Berne and Levy Physiology; updated 6th edition, Page no: 9', 'role': 'assistant'}]
