Why does facilitated diffusion happen:
~ It regulates what goes in and what goes out of the cell
~The cell membrane is permeable to only a select few types of molecules and the molecules that are allowed to move across the cell membrane must be non-polar molecules which are small in size
What direction the particles diffuse in:
~From one side of the membrane where the substrate concentration is high to the other side of the membrane where the concentration is lower
~Diffuses across membranes down the concentration gradient
The molecules that help in this process:
~carbohydrates, amino acids, nucleosides, and ions
Hope this helped you- have a good day bro cya)
