Each of the following is true for the mechanism of the Na⁺/K⁺ ATPase pump except

A)the E2 conformation is open to the outside of the cell and has high affinity for K⁺.
B)the E1 conformation is open to the inside of the cell and has high affinity for Na⁺.
C)Na⁺ triggered phosphorylation of the pump stabilizes the E2 conformation.
D)K⁺ triggered dephosphorylation of the pump stabilizes the E2 conformation.
E)Each E1-E2 cycle pumps 3 Na⁺ ions out and 2 K⁺ ions in.
