No, simple diffusion does not require the use of channels. It is the process by which molecules move across a membrane directly through the lipid bilayer, driven by concentration gradients. This means that small, nonpolar molecules like oxygen and carbon dioxide can freely pass through the membrane without the need for protein channels. However, for larger or polar molecules, facilitated diffusion using channels or carriers is necessary.

What action does not require the cell to use ATP?
Diffusion does not require the use of any ATP.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What are the similarities between diffusion and facilitated diffusion?
Diffusion is the main method by wich small molecules move across the cell membrane. while many cellular processes depend on osmosis because cells cannot function properly without adequate water. Facilitated diffusion works through channels and Osmosis only works with water.
The majority of water molecules moving across plasma membranes by osmosis do so via a process that is most similar to?
The majority of water molecules moving across plasma membranes by osmosis do so via a process that is most similar to facilitated diffusion. This process involves the use of specialized protein channels called aquaporins, which facilitate the rapid movement of water molecules across the hydrophobic lipid bilayer of the membrane. Unlike simple diffusion, which occurs directly through the membrane, facilitated diffusion requires these specific channels to enhance the transport efficiency of water.
What action does not require the cell to use ATP?
Diffusion does not require the use of any ATP.
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
What are the 2 types of diffusion and explain fully?
The two types of diffusion are passive diffusion and facilitated diffusion. Passive diffusion is the movement of molecules across a membrane without the need for a protein carrier, driven by the concentration gradient. Facilitated diffusion involves the use of specific protein channels or carriers to help molecules move across the membrane, still following the concentration gradient without requiring energy.
How does Facilitated diffusion differs from diffusion in that facilitated diffusion?
Facilitated diffusion involves the use of carrier proteins to move specific molecules across the cell membrane, while simple diffusion does not require proteins and involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion is selective and allows for faster transport of specific molecules that may be too large or polar to diffuse freely through the membrane.
What does facilitated diffusion require the use of?
Mo
Does the facialited diffusion require the cell to use energy?
No, it does not require energy use from the cell.
Why is facilitated diffusion faster than simple diffusion?
Facillatated diffusion is faster than simple diffusion when solute concentration is low because it uses channels to transport molecules throught the lipid bilayer. Simple diffusion depends upon concentration gradients so the net movement of diffusing molecules depends on the concentration gradient, thus the rate of diffusion is directly proportional to the concentration gradient. Simple diffusion is also a type of passive transport, which requires no energy input, whereas facilitated diffusion is protein mediated transport. Passive diffusion of solute into a cell is linearly related to the concentration of solute outside the cell. Carrier proteins increase the rate of diffusion by allowing more solute to enter the cell. Facilitated diffusion, however, approaches a maximum rate as the carrier proteins become saturated with solute.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
Does facilitated diffusion require the use of special membrane proteins?
no
Is diffusion an active transport?
no it is not because it does not require the use of ATP
