What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What type of diffusion helps glucose enter the cell?
facilitated diffusion
How is facilitated diffusion diferant froma an active transport?
Facilitated diffusion is a type of passive transport which does not require the cell to expend energy.
What is the basic difference between simple diffusion and facilitated diffusion across a cell membrane?
The basic difference between simple diffusion and facilitated diffusion lies in the mechanism of transport. Simple diffusion involves the movement of small, nonpolar molecules directly across the lipid bilayer of the cell membrane without the need for protein assistance, driven by a concentration gradient. In contrast, facilitated diffusion requires specific transport proteins, such as channels or carriers, to help larger or polar molecules cross the membrane, also following a concentration gradient. Both processes are passive and do not require energy.
Why the line-with-gaps model is not suitable to explain facilitated diffusion?
Facilitated diffusion is a carrier-mediated form of transport across a membrane. The line-with-gaps model doesn't show the carrier proteins that are in the cell membrane. These proteins are what help facilitated diffusion occur.
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.
What is the similarity between simple diffusion and facilitated diffusion?
both need transport protein
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
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 similarities between facilitated diffusion and active transport in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion and active transport are both methods of transporting molecules across the cell membrane. They both involve the use of specific carrier proteins to facilitate the movement of molecules. However, the key difference is that facilitated diffusion does not require energy input from the cell, while active transport does require energy in the form of ATP to move molecules against their concentration gradient.
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.
What are the similarities between active transport and facilitated diffusion in terms of their mechanisms of transporting molecules across the cell membrane?
Both active transport and facilitated diffusion are mechanisms that transport molecules across the cell membrane. They both involve the movement of molecules from an area of higher concentration to an area of lower concentration. However, active transport requires energy input from the cell to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules pass through the membrane.
