It allows for the flow of substances which are normally too large to pass through the cell membrane. Like active transport, it accomplishes this using channel proteins coded for each specific substance (sugar, for example). Unlike active transport, facilitated diffusion only works WITH the osmotic pressure gradient, not against.
What else can I help you with?
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
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.
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
How much ATP does the Facilitated diffusion cost the cell?
Facilitated diffusion is an inactive mode.So no ATP cost.
What type of diffusion helps glucose enter the cell?
facilitated diffusion
What occurs in Facilitated diffusion?
movement. In a cell.
How do products of the cell get out of the cell?
Diffusion, facilitated diffusion, passive transport, facilitated transport (?) and active transport ... unless we are referring to viral or bacterial products.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
What moves substances into and out of the cell in facilitated diffusion?
coffee
