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.
In what process are carrier proteins important?
Carrier proteins is important in facilitated diffusion. Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.
In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
Can polar molecules cross the cell membrane?
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
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 is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
In what process are carrier proteins important?

Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.
In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
What is facilitated transport?
Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
What are the 3 methods of passive transport?
The three methods of passive transport are simple diffusion, facilitated diffusion, and osmosis. Simple diffusion involves the movement of molecules across a membrane from an area of high concentration to low concentration. Facilitated diffusion uses carrier proteins to help larger or charged molecules move across the membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
Can polar molecules cross the cell membrane?
Yes, polar molecules can cross the cell membrane through facilitated diffusion or active transport.
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What includes diffusion osmosis and facilitated diffusion?
These processes involve the movement of molecules across a semi-permeable membrane. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Facilitated diffusion is the passive transport of molecules across a membrane with the help of specific proteins.
How do most molecules cross the cell membrane?
Most molecules cross the cell membrane through passive diffusion, facilitated diffusion, or active transport. Passive diffusion relies on the concentration gradient, facilitated diffusion involves the use of protein channels or carriers, and active transport requires energy to move molecules against their concentration gradient.
