The most immediate result of ATP hydrolysis for the sodium/potassium ATPase is the... binding of ADP release of K+ release of Na+ binding of K+

In considering active transport by Na + -K + -ATPase at body temperature (37 o C), 3 Na+ are pumped out of the cell and 2 K + are pumped in for each ATP that is hydrolyzed to ADP + P i . Given that underyour experimental conditions, the DG for ATP hydrolysis is -10 kcal/mol, and that V is -60 mV, and that the pump maintains the internal Na + at 10mM, external Na + at 120 mM, internal K + at 120 mM and external K + at 8mM, what is the efficiency of the pump (i.e., what fraction of the energy available from ATP hydrolysis is required to drive transport at the provided levels)?

You are considering transport of Fe3+ out of a biological cell with a membrane potential of -60 mV. What is the value for delta psi in this case? (Make sure you express this value in proper units, i.e., as you would enter this value into the change in free energy of transport equation.)

What provides the energy for the H+ to be pumped against the concentration  gradient.?
