What uses carrier proteins to transport molecules across a semi-permeable membrane?
Carrier proteins in a cell surface (plasma) membrane will carry specific molecules or molecular ions (by facilitated diffusion) through that connot diffuse through the membrane accross a concentration gradient. their are many different types of protein carriers in different cells around the body. in the nephron of a kidney, in the PCT, the cells that line this part of the tubule contain co-transporter proteins that allow facilitated diffusion for both Na+ ions and Glucose to enter at the same time. there are also similar carrier proteins here for Na+ and amino acids. i could keep going but i would be here for a while, they all work differently but if your looking for the mechanism. mostly its by facilitated diffusion, some are just diffusion, actively transported, pumped or osmosis. but you must be specific as to what type of carrier protein is transporting what material.

What biomolecule helps transport molecules across the membrane?
proteins
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What does a cell membrane have that makes it easier for certain molecules to cross the cell membrane?
Cell membranes have proteins like channel proteins and carrier proteins that facilitate the transport of certain molecules across the membrane. These proteins provide specific pathways for molecules to pass through, making it easier for them to cross the membrane. Additionally, some molecules can cross the membrane through simple diffusion if they are small and non-polar.
What helps molecules diffuse across membrane through transport proteins?
Transport proteins help facilitate the movement of molecules across a membrane by providing a specific channel or carrier for the molecules to pass through. These proteins can be selective, allowing only certain molecules or ions to pass through, and can also be regulated based on the cell's needs. Additionally, transport proteins can function through processes such as facilitated diffusion or active transport to move molecules in or out of the cell.
What biomolecule helps transport molecules across the membrane?
proteins
What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules involved in cell transport include carrier proteins, channel proteins, and pump proteins. Carrier proteins bind to specific molecules and transport them across the membrane, channel proteins form channels for molecules to pass through, and pump proteins use energy to actively transport molecules against a concentration gradient.
What do the channel proteins in the cell membrane do?
Channel proteins, a type of transport proteins to the cells, move molecules from outside of the membrane to the inside
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.
How do transport proteins make make it easier for certain molecules to diffuse across a membrane?
Facilitated diffusion is the diffusion of molecules.across a membrane through transport proteins. Transport proteins make it easier for molecules to enter or exit acell. But the process is still a form of passive transport.
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
How do transport proteins work?
They are used in Facilitated Diffusion, helping to transport ions, macromolecules, and other substances incapable of entering a cell by themselves to cross through the plasma membrane of the cell.
What are function of membrane proteins?
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.

What can not cross the semipermeable membrane?
Large molecules such as proteins and polysaccharides cannot easily cross a semipermeable membrane due to their size. Additionally, charged molecules like ions may have difficulty crossing depending on the membrane's properties. Lipid-soluble molecules, gases, and small uncharged polar molecules can usually pass through more easily.
