Based on this information, the substances will move directly across the membrane from inside the cell to outside the cell (D).
What is simple diffusion?
It is a diffusion process through the membrane that consists of the passage of a substance through the biological membrane as a function of the concentration gradient.
Molecules and ions can cross the membrane passing from the area of higher concentration to the area of lower concentration.
Therefore, we can conclude that based on this information, the substances will move directly across the membrane from inside the cell to outside the cell (D).
