Which Best Explain How Simple Diffusion Differs From Facilitated Diffusion
The main difference between facilitated diffusion and active transport is that facilitated diffusion occurs through a concentration gradient whereas active transport occurs against the concentration gradient by using energy from ATP. Simple diffusion is mostly involved in the passage of small non-polar molecules. Facilitated Diffusion Definition Principle Factors Examples Simple diffusion does not require the assistance of a carrier molecule. . Movement of small molecules like water across cell membrane. Na Ions move easily through water which is polar but cannot pass directly through the lipid nonpolar part of the cell membrane. Movement of water across the plasma membrane in the direction of the more extremely focused impenetrable solutes either by crossing the plasma membrane straight or by moving through a channel protein. 2Facilitated diffusion is an example of a passive simple diffusion. In facilitated diffusion mole...
