It's often used to transport nutrients across the epithelium of the gut. It's also used to reabsorb nutrients from filtrate in the kidney. Any time the body needs to move substances against their concentration gradient without wasting excess ATP, you might expect cells to use facilitated diffusion. Facilitated diffusion usually requires less ATP per molecule moved than does active transport.
What else can I help you with?
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.
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 process is used to move sugar molecules across a cell membrane?
The process used to move sugar molecules across a cell membrane is called facilitated diffusion. This process involves the use of transport proteins in the cell membrane to help facilitate the movement of sugar molecules from an area of higher concentration to an area of lower concentration, without requiring energy input from the cell.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
How are diffusion and active transport different?
There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient. That is, when an area has more concentration than the other area. Diffusion is used to transfer particles from one place to another. Active transport is used to transfer particles, usually occurring against a concentration gradient. Active transport requires energy to occur however, diffusion does not. There are two types of diffusion. Facilitated and non facilitated. Diffusion occurs when there is a concentration gradient.

When are transport proteins used?
During facilitated diffusion

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.
What is used in facilitated diffusion to assist the transport of sugar and sodium?
transport proteins both are carrier proteins and channel proteins
What type of passive transport is shown is the transparency?
Facilitated diffusion because carrier proteins are being used.
When does facilitated diffusion occur?
Facilitated diffusion occurs when molecules move across a cell membrane with the help of specific transport proteins. This process is used to transport large, polar, or charged molecules that cannot pass through the lipid bilayer unaided.
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 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.
Does facilitated diffusion require ATP?
In cells, passive diffusion is energy independent and therefore does not require ATP. This is opposed to active transport which requires either energy in the form of ATP or a charge gradient to move a molecule or ion across the membrane.
Amino acids absorbed through two processes of?
Amino acids are absorbed through two processes: active transport and facilitated diffusion. Active transport requires energy and is used for absorption of essential amino acids, while facilitated diffusion does not require energy and is used for absorption of non-essential amino acids. Both processes occur in the small intestine.
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.
