Mercedes Reynolds · Answer 1

Both sodium and potassium ions are transported against their concentration gradients

Explanation:

In the cell, the sodium potassium pump is a type of transport, of the active type.

It requires an energy expenditure and always goes against gradient.

For every 3 Na + that leave, 2 K + enter and the action hydrolyzes an ATP (ADP + P)
