Facilitated diffusion is used in the kidneys primarily in the proximal convoluted tubule, where it aids in the reabsorption of glucose, amino acids, and other solutes. Specific transporter proteins in the renal tubular cell membranes facilitate the movement of these substances from the tubular fluid back into the bloodstream without requiring energy. This process is essential for maintaining the body’s nutrient balance and preventing loss of essential molecules in urine. Additionally, facilitated diffusion is also involved in the reabsorption of certain ions, such as potassium and sodium, through specific channels.
What else can I help you with?
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
When are transport proteins used?
During facilitated diffusion
When would facilitated diffusion be used?
Facilitated diffusion is used when molecules need to move across a cell membrane from an area of high concentration to an area of low concentration, but cannot pass through the lipid bilayer on their own. In facilitated diffusion, carrier proteins or channel proteins help facilitate the movement of these molecules across the membrane.
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 type of diffusion helps glucose enter the cell?
facilitated diffusion
Is this true that Facilitated diffusion would be used on large molecules?
its false, facilitated diffusion would be used on small molecules
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
When are transport proteins used?
During facilitated diffusion
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
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.
Facilitated diffusion required what?
Facilitated diffusion requires membrane proteins
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
What is the use of carrier proteins for diffusion?
facilitated diffusion.
How much ATP does the Facilitated diffusion cost the cell?
Facilitated diffusion is an inactive mode.So no ATP cost.
When would facilitated diffusion be used?
Facilitated diffusion is used when molecules need to move across a cell membrane from an area of high concentration to an area of low concentration, but cannot pass through the lipid bilayer on their own. In facilitated diffusion, carrier proteins or channel proteins help facilitate the movement of these molecules across the membrane.
