How do proteins and polysaccharides that are too large to move into a cell through diffusion or active transport move in by?

Using endocytosis or exocytosis. A part of the plasma membrane known creates a "vesicle" around the piece of protein and brings it inside the cell. The opposite occurs during exocytosis. Think ex = exit and en = enter.

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.
The movement of particles through proteins against the normal direction of diffusion?
active transport
Polysaccharides cross the plasma membrane through diffusion?
Yes, carbohydrates can diffuse through a plasma membrane. Proteins can also pass through the fluid membrane, as well as a few other things.
How do most molecules cross the cell membrane?
Diffusion or if the molecules are too large they go through the transport proteins.
What is the function of a transport protein?
Transport protein provide channels for certain solutesTransport proteins are embedded in cellular membranes. They permit the passage across the membrane of substances that cannot pass through the phospholipid bilayer.Substances may pass through transport proteins by diffusion (often called facilitated diffusion because these substances cannot pass through any other part of the membrane) or by active transport.Transport proteins are subdivided into categories, such as channel proteins and carrier proteins, depending on details of their functioning.
How do proteins and polysaccharides that are too large to move onto a cell through diffusion or active transport move into the cell by?
Endocytosis.
Facilitated diffusion moves large molecules through?
Transport proteins and carrier proteins

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.
Does simple diffusion require transport proteins?
no, but active transport on the other hand, does require transport proteins to transport the large molecules into the cell.
The movement of particles through proteins against the normal direction of diffusion?
active transport
Does facilitated diffusion use transport proteins?
Passive diffusion across lipid bilayers :Small apolar molecules like O2 and C02, or ethanol diffuse across the bilayer.Polar or charged molecules do not cross the membraneActive transport :Membrane proteins, such as pores, canals, transporters, facilitators regulate diffusion across membranes.Within membranes :Lipid and proteins diffuse laterally (on the membrane plane).
How do transport proteins move substances across membranes?
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport, facilitated by integral proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.*This is from Wikipedia.....
What do transport dos?
Transport proteins help move (or "transport") large molecules that aren't able to pass through a cell's membrane, through said cell membrane through means of diffusion.
What does active transport and facilitated diffusion have in common?
Active transport is when proteins move substances into the cell while expending energy. Facilitated diffusion is the movement of chemicals through a protein into a cell.
Polysaccharides cross the plasma membrane through diffusion?
Yes, carbohydrates can diffuse through a plasma membrane. Proteins can also pass through the fluid membrane, as well as a few other things.
The movement of molecule down a concentration gradient through transport proteins in the cell membrane is a type of?
facilitated diffusion.
