Question

why is it important to have two systems(active transport and facilitated) of transport?

Answer 1

Active and Passive transport is important for cells because it controls what enters and exits the cell.

Passive transport of materials to and fro is controlled by the permeable cell membrane.

Active Transport allow spontaneous passage of some materials with the use of energy. This is because passive transport can only allow so much materials to come through the cell due to no use of energy.
