Did NaCl require a transport protein?
Did NaCl require a transport protein for diffusion?
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.
Does facilitated diffusion require a carrier or channel protein for the movement of molecules across the cell membrane?
Yes, facilitated diffusion requires a carrier or channel protein for the movement of molecules across the cell membrane.
Does simple diffusion require a helper protein?
No, simple diffusion does not require a helper protein. It is the passive movement of molecules across a cell membrane from an area of higher concentration to an area of lower concentration, relying on the concentration gradient. This process occurs directly through the lipid bilayer of the membrane for small, nonpolar molecules like oxygen and carbon dioxide.
What is the difference between facilitated diffusion with the help of a carrier molecule with the help of a transport protein?
Facilitated diffusion is a type of passive transport (does not require energy). It is called facilitated diffusion because it utilises the carrier protein to diffuse through it. Active transport requires energy to pump certain big molecules to cross over and this uses transport protein. Basically, the difference is just the usage of energy.
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
Why does NaCl not require a transport protein for diffusion?
NaCl can diffuse freely across cell membranes through ion channels or transporters that allow for passive movement down its concentration gradient. As a small and simple molecule, NaCl does not require a specific transport protein for diffusion like larger or more complex molecules.
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.
Are protein carriers or channels involved for diffusion?
Diffusion is the movement of molecules from an area of higher concentration to one of lower concentration and typically does not require protein carriers or channels. However, facilitated diffusion, a specific type of diffusion, does involve protein carriers or channels to help transport molecules, such as ions or larger polar molecules, across the cell membrane. These proteins assist in moving substances that cannot easily pass through the lipid bilayer due to their size or polarity.
What is ATP used for in diffusion?
It's not. Diffusion does not require energy.
Does osmosis require protein?
Nope! Osmosis is simply the movement of H2O over a membrane from high concentration to low concentration. It's a form of passive diffusion!
What is the difference between diffusion and facilitate diffusion?
The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.
