Solution
Simple diffusion in/out of the cell is driven by an electrochemical gradient.
Here's a step-by-step explanation:
-
Simple diffusion is a passive process, meaning it does not require any energy input from the cell.
-
It is driven by the electrochemical gradient, which is a form of potential energy stored in the difference in concentration of an ion or molecule across the cell's membrane.
-
This gradient is created by the difference in the concentration of ions or molecules inside and outside the cell.
-
Molecules or ions will naturally move from an area of high concentration to an area of low concentration, which is what we call diffusion.
-
In the case of the cell, molecules or ions will move across the cell membrane until the concentration is equal on both sides of the membrane. This movement is what
