What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What is the eventual result of diffusion describe concentration prior to and at this point?
The eventual result of diffusion is equilibrium. The concentrations prior to this point would be uneven. The solutes then diffuse from areas of high solute concentration to areas of low solute concentration. After diffusion, at equilibrium, the concentration will be even in different areas.
Why do solutes move across a lipid bilayer?
Solutes can move across a lipid bilayer through passive diffusion, facilitated diffusion, or active transport. Passive diffusion occurs when solutes move down their concentration gradient, facilitated diffusion involves the use of transport proteins, and active transport requires energy to move solutes against their concentration gradient.
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.
Is the final equilibrium state the same for a molecule that enters by facilitated diffusion as for one that enters by diffusion?
Yes
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
Does diffusion cause a concentration gradient?
Diffusion is the result of a concentration gradient. When there is a higher concentration of a substance on one side of a barrier than on the other side, the molecules move across the barrier to try and establish equilibrium. This process is diffusion. Diffusion of water is specifically called osmosis. While diffusion occurs in living things, equilibrium is never reached. In an organism, equilibrium is the result of death.
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
What is the eventual result of diffusion describe concentration prior to and at this point?
The eventual result of diffusion is equilibrium. The concentrations prior to this point would be uneven. The solutes then diffuse from areas of high solute concentration to areas of low solute concentration. After diffusion, at equilibrium, the concentration will be even in different areas.
What particle movement from an area of higher concentration to an area of lower concentration?
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. This process is driven by the natural tendency of particles to spread out and achieve equilibrium.
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 is the overall goal of diffusion osmosis and facilitated diffusion?
The overall goal of diffusion, osmosis, and facilitated diffusion is to achieve equilibrium by moving substances across cell membranes. Diffusion involves the passive movement of molecules from an area of higher concentration to lower concentration. Osmosis specifically refers to the movement of water across a semi-permeable membrane to balance solute concentrations. Facilitated diffusion uses specific transport proteins to help molecules that cannot easily cross the membrane to move down their concentration gradient.
What is the eventual result of the cellulare process of diffusion?
the eventual result of cellular deffusion is dynamic equilibrium. - answered by Duncan Lint
