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

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.
