What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
What else can I help you with?
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 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.
Is carrier proteins active or a passive transport?
Carrier proteins are involved in facilitated diffusion, a type of passive transport. They bind to specific molecules and assist in their movement across the cell membrane down their concentration gradient without requiring energy input from the cell.
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
What is the facilitated diffusion to assist the 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.
In what type of passive cell membrane transport do carrier proteins combine with specific molecules to assist them across the membrane?
Facilitated Diffusion
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.
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 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.
What types of solute molecules may be moved by facilitated diffusion?
Facilitated diffusion can transport polar molecules, ions, and large molecules that cannot pass through the cell membrane unaided. Examples include glucose, amino acids, and ions like potassium and chloride. Transport proteins like channels and carriers assist in the movement of these solutes across the cell membrane.
What is used in facilitated diffusion to assist the transport of sugar and sodium?
transport proteins both are carrier proteins and channel proteins
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.
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.
How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the 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.
