"Fox 5" No, this is not correct. The correct answer is "passive diffusion".
facilitated diffusion
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.
Facilitated diffusion helps molecules move across cell membranes by utilizing specific carrier proteins. It does not require energy input, as molecules move down their concentration gradient. This process is crucial for transporting larger molecules like glucose and ions across cell membranes.
The type of molecular movement that involves one-way diffusion across a semipermeable membrane is called osmosis. Osmosis specifically refers to the diffusion of water molecules from an area of lower solute concentration to an area of higher solute concentration through the membrane. This process helps to balance solute concentrations on both sides of the membrane and is crucial for maintaining cellular homeostasis.
Materials cross the plasma membrane through processes such as simple diffusion, facilitated diffusion, and active transport. These processes involve the movement of substances across the lipid bilayer of the membrane with the help of transport proteins or by utilizing energy to move against a concentration gradient.
An example of an integral membrane protein that helps move molecules across a cell membrane is a transporter protein. These proteins are embedded within the lipid bilayer and facilitate the movement of specific molecules such as ions or metabolites across the membrane through a process called facilitated diffusion or active transport.
A substance can enter a cell through diffusion, facilitated diffusion, active transport, endocytosis, or passive transport. Each of these processes has different mechanisms for moving substances across the cell membrane.
Osmosis is the special kind of diffusion that water undergoes, where water molecules move across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process helps to balance the concentration of solutes on either side of the membrane.
1. facilitative diffusion-transport proteins provide a pathway for certain molecules to pass 2. osmosis-the passive transport of water across a selectively permeable membrane 3. diffusion- the net movement of the particles of a substance from where they are more concentrated to where they are less concentrated. (out of a sophomore Biology book)... hope this helps <3
Glucose transport across cell membranes using glucose transporters, and water movement through aquaporin channels are examples of facilitated diffusion. These processes involve the movement of molecules across the membrane with the help of specific carrier proteins.
The membrane allows it and cytoplasm also helps it.
