The Membrane Transport Protein Na+-K+ ATPase Carries Both Na+ and K

Multiple Choice

The membrane transport protein Na+-K+ ATPase carries both Na+ and K+ ions across the plasma membrane.Typically the concentration of K+ inside cells is about 30 times higher inside the cell than outside.The concentration of Na+ is about 20 times less inside the cell than outside.Based on this information,which statement below is false?

A) The proper functioning of Na+-K+ ATPase could serve as an energy source for secondary active transport proteins.
B) It is a symport.
C) Transport of Na+ and K+ must be coupled to an exergonic reaction.
D) Na+-K+ ATPase likely undergoes conformational changes during transport.
