The sodium-potassium pump can transport the sodium-potassium pump can transport only if sodium and potassium are available sodium even if potassium is not available potassium even if sodium is not available sodium even if potassium is not available and potassium even if sodium is not available

The correct answer is: only if sodium and potassium are available.

The sodium-potassium pump is an enzyme that uses the chemical energy stored in ATP molecules to export 3 sodium ions out of the cell and to import 2 potassium ions into the cell. This happens simultaneously, so the presence of both of the ions is necessary.  

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
