A cell uses active transport to move sodium ions out of the cell. Why does the cell use active transport instead of diffusion to move sodium ions out of the cell?.

A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.

The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.

WHAT IS ACTIVE TRANSPORT?

Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.

This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.
