What is the importance of passive and active transport to the cell?

Answer 1

It is passive because it does not require energy when moving molecules. It is passive because it does not require energy when moving molecules. There is both active and passive transport. If it is going against the concentration gradient it is active transport. If it is not acting against the concentration gradient it is passive transport.

Answer 2

1- three sodium ions enter the channel from within the cell( intracellular Na2+)

2-ATP polyphosphates the channel causing it to pump the three sodium ions out from the cell

3-two potassium ions enter the channel from the outside (extracellular K+)

4-the now unphosphorylated channel pumps the 2 potassium ions into the cell

Answer 3

Ions cannot pass though the hydrophobic interior of the lipid membrane so channels are necessary for both active and passive transport across membrane.

Answer 4

Either they can pass through the plasma membrane or the ion channels open up and let stuff pass through. <3

Answer 5

in order to move in/out of the cell.

active transport is the movement of alcer
