Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?
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.
Is the movement of water from high to low concentration through a membrane?
Yes, the movement of water from an area of higher concentration to an area of lower concentration through a selectively permeable membrane is called osmosis. It helps in balancing the concentration of solutes on both sides of the membrane.
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.
Are diffusion and osmosis types of active transport?
No, diffusion and osmosis are passive transport processes, not active transport. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis is the movement of water across a selectively permeable membrane. Active transport, on the other hand, requires energy and moves substances against their concentration gradient.
What is the relationship between the electrochemical gradient and the concentration gradient in cellular transport processes?
The electrochemical gradient is a combination of the electrical gradient and the concentration gradient. It influences the movement of ions across cell membranes during cellular transport processes. The concentration gradient refers to the difference in the concentration of ions or molecules inside and outside the cell, while the electrical gradient refers to the difference in charge across the cell membrane. Together, they determine the direction and rate of ion movement in cellular transport processes.
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 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.
Why is no energy required in passive transport processes?
In passive transport processes, no energy is required because molecules move across the cell membrane from an area of high concentration to an area of low concentration, following the natural flow of diffusion. This movement occurs spontaneously and does not require the cell to expend energy.
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 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 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 is active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
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 are the similarities between simple and facilitated diffusion in terms of their mechanisms of transport across the cell membrane?
Both simple and facilitated diffusion are passive processes that involve the movement of molecules across the cell membrane from an area of high concentration to an area of low concentration. They do not require energy input from the cell. In both processes, molecules move through specific channels or carrier proteins in the cell membrane to facilitate their transport.
