You have isolated the Na/K-ATPase in a semi-purified membrane system. Given higher concentrations of Na' out and higher K inside, addition of ATP to the inside leads to increases of Nat olutside and Kt inside as expected. If instead, you add the ATP to the outside of the membrane, you don't see any change in the ion levels. Why? •...
