| Characteristics | Simple Diffusion | Facilitated Diffusion |
|---|---|---|
| Size of molecules | Simple diffusion is involved in the passage of small molecules along with non-polar molecules. | Facilitated diffusion is commonly involved in the movement of large as well as polar molecules across a biological membrane. |
Q. Why is facilitated diffusion similar to simple diffusion?
Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
Q. What is the difference between simple and facilitated diffusion?
In simple diffusion, the movement of particles occurs along the direction of the concentration gradient. In facilitated diffusion, the movement of molecules can occur both in direction and opposite of the concentration gradient. Simple diffusion is mostly involved in the passage of small non-polar molecules.
Q. How do molecules move in simple diffusion?
In simple diffusion, small noncharged molecules or lipid soluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient).
Q. Does facilitated diffusion use a protein channel?
Facilitated diffusion is the diffusion of solutes through transport proteins in the plasma membrane. Channel proteins, gated channel proteins, and carrier proteins are three types of transport proteins that are involved in facilitated diffusion.
Q. What is facilitated diffusion a type of?
Facilitated diffusion is one of the many types of passive transport. This means that it is a type of cellular transport where substances move along their concentration gradient.
Q. What is the difference between simple diffusion and facilitated diffusion quizlet?
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. In simple diffusion, the substance passes between the phospholipids; in facilitated diffusion there are specialized membrane channels.
Q. Why is facilitated diffusion a passive process?
Being passive, facilitated transport does not directly require chemical energy from ATP hydrolysis in the transport step itself; rather, molecules and ions move down their concentration gradient reflecting its diffusive nature.
