What is the similarity between simple diffusion and facilitated diffusion?

Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient. The difference is how the substance gets through the cell membrane. Charged or polar molecules that cannot fit between the phospholipids generally enter and leave cells through facilitated diffusion.

What is the main similarity and main difference between simple diffusion and facilitated diffusion?

In simple diffusion, the molecules can pass only in the direction of concentration gradient. In facilitated diffusion, the molecules can pass both in direction and opposite of the concentration gradient. Simple diffusion permits the passage of only small and nonpolar molecules across the plasma membrane.

What are the similarities between facilitated diffusion and active transport?

Both facilitated diffusion and active transport need a concentration gradient to occur. Both of them are capable of transporting ions, sugars, and salts. They are also similar in the way that they use membrane proteins as transport vehicles.

What is the difference between simple diffusion and facilitated diffusion Brainly?

Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient. Simple diffusion is found only in prokaryotes while facilitated diffusion is found only in eukaryotes.
