Cell Transport

A solution that has a lower concentration of solutes compared to another solution, leading to water moving into the cell, causing it to swell.

The movement of materials across a cell membrane without the use of energy, typically from an area of high concentration to an area of low concentration.

The process of passive transport of molecules across a biological membrane via specific transmembrane integral proteins.

The movement of molecules against their concentration gradient, requiring energy, usually in the form of ATP.

A solution that has a higher concentration of solutes compared to another solution, causing water to move out of the cell, leading to cell shrinkage.

A solution that has the same concentration of solutes as another solution, resulting in no net movement of water into or out of the cell.

The diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

The difference in the concentration of a substance across a space, which drives the movement of substances during diffusion.

Protein channels facilitate the movement of specific molecules across the cell membrane, often during facilitated diffusion.

Simple diffusion occurs directly through the membrane, while facilitated diffusion requires specific protein channels to assist the movement of molecules.
