Question

Which statements correctly describe how the sodium-potassium pump works?
Select all that apply.

Potassium inside the cell is pumped out while sodium outside the cell is pumped in.

Sodium follows its concentration gradient, while potassium is moved against its concentration gradient.

The pump transports the two types of ions in different directions.

ATP provides the energy to operate the motion of the pump.

Answer 1

From Internet:

The sodium-potassium pump works by pumping two potassium ions into the cell and pumping out three sodium ions using the energy from an ATP molecule. This leads to a build-up of considerable differences in the concentration of the ions on the outside and inside of the cell.

Answer 2

The pump transports the two types of ions in different directions.

ATP provides the energy to operate the motion of the pump.
