Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?

∙ 13y ago
No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.

Movement through a cell membrane without using energy is?
passive transport, which includes processes like diffusion and osmosis. These processes rely on the natural movement of molecules from an area of higher concentration to lower concentration, and do not require the cell to use energy to facilitate the movement.
What two processes transport materials through the semi permeable membrane?
Two processes that transport materials through a semi-permeable membrane are passive diffusion, which involves the movement of molecules from an area of high concentration to an area of low concentration, and facilitated diffusion, which involves the transport of molecules across the membrane with the help of specific carrier proteins.
What is the movement across a membrane with the help of ATP?
Active transport is the movement of molecules across a membrane with the help of ATP, which provides the energy needed for the transport process. This allows substances to move against their concentration gradient, from an area of lower concentration to an area of higher concentration.
What requires no energy to move molecules across a membrane?
Passive transport, such as diffusion, osmosis, and facilitated diffusion, does not require energy to move molecules across a membrane. These processes rely on the concentration gradient to drive the movement of molecules from an area of higher concentration to an area of lower concentration.
What helps to allow materials to cross the plasma membrane?
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.

passive transport, which includes processes like diffusion and osmosis. These processes rely on the natural movement of molecules from an area of higher concentration to lower concentration, and do not require the cell to use energy to facilitate the movement.
Does osmosis involve transport proteins?
No, osmosis does not involve transport proteins. Osmosis is the passive movement of water across a selectively permeable membrane in response to a concentration gradient. Transport proteins are involved in facilitated diffusion and active transport processes.

What is the movement of material through a membrane?
The movement of material through a membrane can occur via passive processes such as diffusion and osmosis, where substances move down their concentration gradient without requiring energy input. Active transport, on the other hand, involves the use of energy to move substances against their concentration gradient. Facilitated diffusion involves the use of carrier proteins to help transport specific molecules across the membrane.
What is the movement of particles diffusion osmosis or active transport?
Active transport is the movement of particles across a cell membrane against the concentration gradient with the help of energy. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, and osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
What do active transport and osmosis have in common?
Both active transport and osmosis are processes that involve the movement of molecules across a cell membrane. However, active transport requires the use of energy to move molecules against their concentration gradient, while osmosis involves the passive movement of water molecules from an area of high water concentration to an area of low water concentration.
What is active transport and passive transport?
Active transport is the movement of molecules across a cell membrane that requires energy in the form of ATP. Passive transport, on the other hand, is the movement of molecules across a cell membrane that does not require energy and occurs down a concentration gradient.
What requires no energy to move molecules across a membrane?
Passive transport, such as diffusion, osmosis, and facilitated diffusion, does not require energy to move molecules across a membrane. These processes rely on the concentration gradient to drive the movement of molecules from an area of higher concentration to an area of lower concentration.
What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient

What includes diffusion osmosis and facilitated diffusion?
These processes involve the movement of molecules across a semi-permeable membrane. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Facilitated diffusion is the passive transport of molecules across a membrane with the help of specific proteins.
How do fluid materials transport through membrane osmosis osmosis?
Fluid materials transport through membrane osmosis by the movement of water molecules across a semipermeable membrane from an area of higher concentration to an area of lower concentration. This process is driven by the concentration gradient of solutes on either side of the membrane. Osmosis helps maintain the balance of fluids and electrolytes in living organisms.
