What biomolecule helps transport molecules across the membrane?
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.
What is another form of transport that uses transport proteins to move other ions and small molecules across the plasma membrane?
This process of transportation might be diffusion. Diffusion, by definition, is the process by which molecules spread out, or move from areas where there is a high concentration of molecules to an area where there is a low concentration of molecules.

What name is given to the trans-membrane proteins that allow the direct passage?
The name given to the trans-membrane proteins that allow the direct passage of small molecules across the cell membrane is "channel proteins." They form channels or pores that facilitate the movement of specific ions or molecules across the membrane.
How do carrier proteins transport substances across membranes?
Carrier proteins bind to specific molecules on one side of the membrane, undergo a conformational change, and release the molecules on the other side. This process allows the substances to be transported across the membrane selectively.
How do carrier proteins facilitate the passive transport of molecules across a membrane?
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
What biomolecule helps transport molecules across the membrane?
proteins
How do you transport proteins in a cell make it easier for certain molecules to diffuse across a membrane?
Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.

What is the process in which certain molecules act as carriers to move materials such as sugar across the cell membrane?
Ions such as sodium, potassium, chloride and calcium. Some molecules that are too big to get through the lipid bilayer by themselves can also be shuttled across the membrane by carrier proteins.
What is it called when transport proteins to help large molecules like glucose across the cell membrane?
Facilitated diffusion is the process by which transport proteins help large molecules like glucose cross the cell membrane. These proteins create a channel or carrier mechanism that allows the molecule to move across the membrane along its concentration gradient.
What is another form of transport that uses transport proteins to move other ions and small molecules across the plasma membrane?
This process of transportation might be diffusion. Diffusion, by definition, is the process by which molecules spread out, or move from areas where there is a high concentration of molecules to an area where there is a low concentration of molecules.

How do carriers proteins facilitate passive transport of molecules across a membrane?
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.

The name given to the trans-membrane proteins that allow the direct passage of small molecules across the cell membrane is "channel proteins." They form channels or pores that facilitate the movement of specific ions or molecules across the membrane.
How do carrier proteins transport substances across membranes?
Carrier proteins bind to specific molecules on one side of the membrane, undergo a conformational change, and release the molecules on the other side. This process allows the substances to be transported across the membrane selectively.
Why must transport proteins be peripheral proteins?
Transport proteins must be peripheral proteins because they need to be able to move within the cell membrane to facilitate the transport of molecules across the membrane. Peripheral proteins are not embedded within the lipid bilayer of the membrane, allowing them to move more freely and interact with molecules on both sides of the membrane. This mobility is essential for transport proteins to effectively transport molecules across the cell membrane.
What role do carrier proteins play in the process of active transport?
Carrier proteins play a crucial role in active transport by helping move molecules across the cell membrane against their concentration gradient. These proteins bind to specific molecules and change shape to transport them across the membrane, requiring energy in the form of ATP.
