Question

How are facilitated diffusion and diffusion similar?

Both processes involve the movement of solute from an area of low concentration to an area of high concentration.

Both processes involve the movement of solute from an area of high concentration to an area of low concentration.

In both kinds of movement across a cell membrane, proteins do not play a role in assisting the passage of compounds and ions through a membrane.

Answer 1

Both Processes involve the mowment of solate from an area of high Concentration to an area of low concentration simple cliffusion- In simple diffusion small noncharged onolecule our lipid Soluble molecules Pass between the phospholipids to entea or leave the cell moving from area of high concentration to Low Concentration. Oxygen and courbon clioxide enten and leaves Cell by simple diffusion. P9100 higher concentration to low concentration Facilitated diffusion - In facilitated cliffusion substences move into our out of cells down this concentration goladent through Porotein Channels in the cell memberaner Pocotester portio B 8 B High concentration to Low Concentration Through protein Channel.

So both simple diffusion and involue movement facilitated diffusion down the concentration are similes in that gradient
