Things can be transported out of cells in multiple ways. The first being diffsion, a type of passive transport (which means it doesn't use energy). In diffsion, molecules move from areas of high concentration to areas of low concentration. If there is a higher concentration inside the cell than outside the cell then you're set. The second way is active transport. Unlike diffusion, active transport uses energy (hence the name 'active transprt'). In the process of active transport molecules move from areas of low concentration to areas of higher concentration. The third and final way is through exocytosis. Exocytosis is used when the material to be released is too big to fit in the cell's channels (passageways in and out of the cell). In exocytosis the material, inside a vacuole, moves to the cell membrane. The cell membrane then fuses with the outer layer vacuole, releasing the material.
What else can I help you with?
How do large polar molecules enter the cell?
Large polar molecules enter the cell through facilitated diffusion or active transport, which require the assistance of specific protein channels or carriers in the cell membrane. These proteins help transport the molecules across the membrane against a concentration gradient or when the molecules are too large to pass through on their own.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
Are masses of cells full of pores?
Cells are not full of pores. Cell membranes have specific transport proteins that allow certain substances to enter or exit the cell. These transport proteins regulate the movement of molecules in and out of the cell, preventing large molecules from freely flowing in and out of the cell.
How do you large molecules and ions pass through the cell membrane?
Recently had a homework on the cell membrane, i do know that larger molecules that cant fit through the polar heads into the cell (like gases can...and small molecules?!) can get through only if they qualify the shape fitting of the channel protein- the one that reaches all the way from the outside to the inside of the membrane. hope this helps
Does the process of endocytosis require energy to transport molecules into a cell?
Yes, the process of endocytosis requires energy to transport molecules into a cell.
What are proteins found in cell membranes that transport large molecules?
carrier molecules
How does a cell move a molecule that is too large transport proteins?
Cells may use mechanisms such as endocytosis to engulf and transport large molecules with the help of specialized transport proteins. These transport proteins facilitate the movement of large molecules across the cell membrane by forming vesicles that enclose the molecules and transport them to their destination within the cell. Once inside the cell, the vesicle can fuse with other cellular compartments to release the molecule for further processing or use.
Why do cell need transport proteins to functions?
Some molecules are too large to pass through the cell membrane without transport proteins.

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.

Large molecules are surrounded by the cell membrane and enter the cell?
Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.
When a Cell uses a 'transmembrane protein gate' in order to get large molecules across the Cell membrane this is known as?
Active Transport of Cellular materials.
Why do cells need to use transport proteins function?
Some molecules are too large to pass through the cell membrane without transport proteins.
