Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
What is the process that occurs when molecules move from an area of low concentration to an area of high concentration, against the concentration gradient?
The process that occurs when molecules move from an area of low concentration to an area of high concentration, against the concentration gradient, is called active transport. This process requires energy to pump molecules across the cell membrane.
What is process that moves molecules across a cell membrane from regions of lower concentration to higher concentration?
The process that can move molecules from a low to a high concentration through a cell membrane is active transport.
Water molecules spreading through a membrane with a change in cell size is an example of?
Osmosis. Osmosis is the process where water molecules move from an area of high water concentration to an area of low water concentration through a selectively permeable membrane, such as a cell membrane.
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
Which process describes the movement of molecules from high concentration to areas of low concentration?
diffusion. novanet.
What process do water molecules cross the cell membrane?
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.
How does the process of diffusion of water molecules across a semipermeable membrane occur?
Diffusion of water molecules across a semipermeable membrane occurs through a process called osmosis. Osmosis is the movement of water molecules from an area of higher concentration to an area of lower concentration, through the semipermeable membrane, in order to equalize the concentration on both sides. This process is driven by the natural tendency of molecules to move from areas of high concentration to areas of low concentration until equilibrium is reached.
Which process describes the movement of molecules from areas high concentration to areas of low concentration?
diffusion. novanet.
Which process describes the movement of molecules from areas of high concentration to areas low concentration?
diffusion. novanet.

Which process would be describe the movement of sugar molecules through membrane from a region of higher concentration to a region of lower concentration?
This process is called passive transport or facilitated diffusion, where sugar molecules move down their concentration gradient without requiring energy input from the cell. Proteins in the membrane facilitate the movement of sugar molecules across the membrane.
What is The process by which small molecules pass through a membrane by moving from an area of high concentration to an area of low concentration is?
This process is called passive diffusion or simple diffusion. It does not require energy input and relies on the concentration gradient to drive the movement of molecules across the membrane.
What is the process of molecules from an area of high concentration to low?
Diffusion describes the spread of molecules through random motion from regions of higher concentration to regions of lower concentration.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
