What two types of molecular movement across membranes require vesicles?
Endocytosis and exocytosis are the two types of molecular movement across membranes that require vesicles. Endocytosis involves the engulfment of molecules or particles into a cell by vesicles formed from the cell membrane, while exocytosis involves the release of molecules or particles out of a cell via vesicles fusing with the cell membrane.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What is the name of the process where materials are moved across a cell membrane?
Active transport.The energy is provided by a high-energy molecule, often ATP.Active transport is used to move a substance against (= up) its concentration gradient.Diffusion is what moves across the plasma membrane. This cannot move across water.
What molecule moves across the phospholipid layer through endocytosis?
In endocytosis, molecules like proteins, lipids, and even viruses can be engulfed by the cell membrane and transported across the phospholipid bilayer in vesicles called endosomes. These vesicles are then processed by the cell to release their contents into the cytoplasm.
What process requires energy to bring molecule across the cell membrane?
active transport
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
What helps moves things across the membrane?
transportation
What channel helps move things across the membrane?
transportation

What moves marerials across the plasma membrane in the direction of the concentration?
Active transportation is the material that across plasma membrane. This makes it flow one way.
Does osmosis use vesicles to help it?
No, osmosis does not involve the use of vesicles. Osmosis is the movement of solvent molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Vesicles are small membrane-bound sacs used in the transport of molecules within a cell.

How do larger molecules move across epithelial membranes in the capillaries?
Larger molecules can cross epithelial membranes in capillaries through processes like transcytosis, where the molecule is taken up by the cell on one side and transported across the cell to be released on the other side. This process often involves vesicles that transport the molecule across the cell.
What requires no energy to move things across the cell membrane?

What do you think its right answer of the question Molecules that are too large to be moved across a cell membrane can be removed from the cell by endocytosis or exocytosis?
The statement is incorrect. Molecules that are too large to be moved across a cell membrane are typically removed from the cell through exocytosis, where they are transported out of the cell in vesicles. Endocytosis is the process by which cells take in substances by engulfing them in vesicles, not removing them.
