How do carrier proteins facilitate the transport of solutes across the membrane during facilitated diffusion?
Carrier proteins facilitate the transport of solutes across the membrane during facilitated diffusion by binding to specific solutes on one side of the membrane, undergoing a conformational change, and then releasing the solutes on the other side of the membrane. This process allows for the movement of solutes across the membrane without the need for energy input.

Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
Is facilitated diffusion reversible?
Yes, facilitated diffusion is reversible because it involves the movement of molecules across a membrane with the help of transport proteins. These transport proteins can facilitate the movement of molecules in both directions depending on the concentration gradient of the specific molecule.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Diffusion with a channel protein?
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
What types of transport mechanisms through the cell membrane are passive?
Passive transport mechanisms through the cell membrane include simple diffusion, facilitated diffusion, and osmosis. These processes do not require energy input from the cell.
What is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
Facilitated diffusion depends on?
Facilitated diffusion depends on the presence of specific transport proteins in the cell membrane that help to transport specific molecules across the membrane. These transport proteins facilitate the movement of molecules down their concentration gradient, without requiring energy input from the cell.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
A form of passive transport that involves membrane proteins to aid in the movement of substances?
Facilitated diffusion is a form of passive transport that involves membrane proteins to aid in the movement of substances across a cell membrane. The membrane proteins act as channels or carriers to facilitate the passage of specific molecules that cannot freely diffuse across the lipid bilayer. This process does not require energy input from the cell.
Is facilitated diffusion reversible?
Yes, facilitated diffusion is reversible because it involves the movement of molecules across a membrane with the help of transport proteins. These transport proteins can facilitate the movement of molecules in both directions depending on the concentration gradient of the specific molecule.
Does facilitated diffusion require a transport protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion does require a transport protein for the movement of molecules across the cell membrane.
Molecules that permeate a plasma membrane by facilitated diffusion is what?
Molecules that permeate a plasma membrane by facilitated diffusion are typically larger, polar molecules that cannot pass through the lipid bilayer unassisted. These molecules rely on specific transport proteins embedded within the membrane to facilitate their movement across the membrane down their concentration gradient.
What are the types of movement through a membrane?
Osmosis, diffusion, facilitated diffusion, active transport
Diffusion with a channel protein?
Channel proteins facilitate the passive movement of molecules down their concentration gradient. They form channels across the cell membrane, allowing specific molecules to move in and out of the cell without requiring energy input. This process is known as facilitated diffusion.
How simple diffusion can be distinguished from facilitated diffusion?
Simple diffusion does not involve the use of transport proteins and relies on the concentration gradient of molecules for movement across the membrane. Facilitated diffusion, on the other hand, requires specific transport proteins to help facilitate the movement of molecules across the membrane, often against their concentration gradient.
What types of transport mechanisms through the cell membrane are passive?
Passive transport mechanisms through the cell membrane include simple diffusion, facilitated diffusion, and osmosis. These processes do not require energy input from the cell.
Which type of transport occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side?
Facilitated diffusion occurs when a membrane protein binds to a molecule on one side of the cell membrane and then releases it on the other side. This type of transport does not require energy and relies on the concentration gradient to move molecules across the membrane.
