Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated diffusion does not require energy but relies on carrier proteins to transport molecules across the cell membrane. The carrier proteins assist in the movement of specific molecules down their concentration gradient.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What happens in the process of facilitated diffusion In what part of the membrane does it take place?
Facilitated diffusion is a passive transport process where molecules move across a cell membrane with the help of specific carrier proteins. These carrier proteins are present in the membrane and assist in the movement of molecules like sugars and amino acids down their concentration gradient. Facilitated diffusion occurs in the lipid bilayer of the cell membrane.
Facilitated diffusion across a biological membrane requires what?
Facilitated diffusion across a biological membrane requires the presence of specific protein channels or carriers to assist in the movement of molecules from an area of high concentration to an area of low concentration. The process does not require energy input from the cell and relies on the concentration gradient to drive the movement of molecules.
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
In what type of passive transport do protein channels assist molecules across the membrane?
In facilitated diffusion, protein channels assist molecules in crossing the cell membrane. This type of passive transport allows substances, such as ions and polar molecules, to move down their concentration gradient without using energy. The protein channels provide a pathway through the lipid bilayer, enabling the selective transport of specific molecules.

In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
The process is called facilitated diffusion. It is a type of passive transport that involves the movement of molecules across a membrane with the help of specific proteins called carrier proteins or channel proteins. These proteins assist the molecules in crossing the membrane by providing a pathway.
How do other molecules pass through the selectively permeable cell membrane?
[Molecules pass through the cell membrane] through a process known as osmosis. ------------------------------------------------------- Yes, osmosis is a great part of diffusion of molecules, but another important factor to consider is the presence of protein channels in the membrane. The cell membrane is actually a lipid bilayer, in which proteins are embedded. Normally, molecules will simply be diffused through these chanells, but in some cases, the protein must be modified in order to allow the molecules to flow. This is called active transport, which requires energy in order to change the shape of the protein and allow the foreign molecule to pass.
What molecules located in the membrane assist with facilitated diffusion?
Protein channels and carrier proteins are molecules located in the membrane that assist with facilitated diffusion. These proteins help facilitate the movement of specific molecules such as ions, sugars, and amino acids across the cell membrane.
A type of passive transport across a cell membrane that requires special carriers is?
Facilitated diffusion is a type of passive transport that requires special carrier proteins to help molecules move across the cell membrane. These carrier proteins assist in the movement of specific molecules that cannot cross the membrane on their own.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
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 does facilitated diffusion requires?
Facilitated diffusion requires the presence of specific carrier proteins embedded in the cell membrane to help transport molecules across the membrane. These carrier proteins assist in the movement of molecules down their concentration gradient without requiring energy input from the cell.
What is a protein used to transport specific substances?
Transport proteins are membrane proteins that assist in the movement of specific substances across biological membranes. Examples include glucose transporters, ion channels, and ATP-binding cassette transporters. These proteins play a critical role in maintaining cellular homeostasis by ensuring the efficient transport of essential molecules into and out of cells.
