What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What is the protein that allows facilitated diffusion of water?
In the facilitated diffusion the transport protein is needed as well in the active transport.
What process the cell must use to allow the protein to enter and why?
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
Is facilitated diffusion type of active transport?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
What happen during the facilitated diffusion?
Facilitated diffusion occurs against the osmotic potential/concentration gradient and requires energy at the expense of the ATP hydrolysis. There are several way in which this diffusion could occur in the cells. The first one being the ion exchangers. The ion exchangers are coupled with ATPase activity and they exchange ion(s) across the membrane. The most classical example of ion exchanger is the Na+/K+ ion exchanger and Ca+ ATPase. Other way of the facilitated diffusion in the ion channel. These could be voltage gated channel that open in response to the change in the membrane potential and the other being ligand gated channel that operate under the effect of ligand binding.
When are transport proteins used?
During facilitated diffusion
What type of passive transport is shown is the transparency?
Facilitated diffusion because carrier proteins are being used.
What is used in facilitated diffusion to assist the transport of sugar and sodium?
transport proteins both are carrier proteins and channel proteins

What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
What is meant by faciliated diffusion?
Facilitated diffusion (or facilitated transport) is a form of passive transport that is facilitated by transport proteins. Most often it is used to transport polarized molecules (such as glucose and amino acids) across the cell membrane.
Does facilitated diffusion require the Cell to use energy?
No, there is no ATP used in facilitated diffusion, because it is a form of passive transport. It only differs from normal diffusion in that it uses transport proteins to move larger or more polar molecules across the membrane of the cell.
Is this true that Facilitated diffusion would be used on large molecules?
its false, facilitated diffusion would be used on small molecules
What process the cell must use to allow the protein to enter and why?
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
What can effect equilibrium shifts?
Active transport/Facilitated Diffusion where energy is used
